- GK: 21 year old spec... the spec has a very long legacy...there is main spec, but we extracted code and key into their own spec. Key and Code spec are more or less done. I've updated the implementation report. There are two independent implementations each mandatory requirements.
- 21:23:07 [marcosc]
- GK: For the core UI spec, the spec was written in a fairly casual style... we need to rewrite it in an algorithmic style. There are a lot of specs depending on this spec (e.g., pointer spec). I've been talking to the editor of pointerlock, and seeing how we can bridge the two. I'm working on the algorithmic draft.
- 21:23:48 [marcosc]
- MC: there is a document available?
- 21:23:58 [marcosc]
- GK: I'll get a link for it... it's linked from the README

- Emilio: where do implementations differ?
- 21:34:13 [marcosc]
- SZ: I'm not sure if there is an interop issue in the wild... but the spec is vague.
- 21:34:34 [marcosc]
- Emilio: So it might be a matter of doing a spec cleanup
- 21:35:07 [marcosc]
- SZ: I think there might be hidden issues, so just want to make sure we get this right. There are some cases might cause issues in the wild.
- 21:35:21 [marcosc]
- SZ: If we could close those three issues, we could get it to CR
- 21:36:56 [marcosc]
- SZ: There is also V2 - it covers eclusion [sic], for security reasons ... it's used in about 4% of page loads. Apple does consider this high on their priority list, but is willing to accept patches.

- 21:42:59 [marcosc]

- 21:52:47 [marcosc]
- MR: big rewrite, modernized the spec to be algorithmic. We also made gamepad objects live. We are looking at adding an event model that satisfy all use cases, specially for cloud gaming clients. We are also looking how we might get raw and events that are tied to requestAnimationFrame().
- 21:53:01 [mattreynolds]
- https://github.com/w3c/gamepad/pull/151
- 21:54:32 [marcosc]
- MC: we added permission-policy "gamepad" with allowed "self", shipped in Firefox. But turned out to be not super web compatible. So we might switch it to "all".
- 21:56:11 [marcosc]
- RG: to what degree does do we tolerate permission policy change? having the policy is better than not having one. But we should have some kind of guidance to help with these issues.

- JB: very quiet 12 months. In 2019, we have good conversations to add new things... then 2020 happened... so we haven't done too much. WebKit implemented `databases`. Several of the new things in "v3" are currently only in Blink and Gecko.

- 22:16:49 [marcosc]
- JB: We did check if batch operations could be performance improvement, but turned out it wasn't so we rolled that back. We are exploring how to make more complex queries more performant. We've had only a very small trickle of feature requests, so we haven't moved on adding anything new. We've been considering making some editorial clarifications. If anyone else is interested in helping edit the spec, then please let me know.
- 22:17:05 [marcosc]
- JB: we talked about maybe publishing a FPWD. We could still do that.

- Intersection observer issue 431
- 22:22:41 [zcorpan]
- https://github.com/w3c/IntersectionObserver/issues/431
- 22:26:48 [marcosc]
- SP: this is issue I filed while specifying lazy loading images... if you have scrollable container, and that container has lazy images, those images will start loading too late. In my ideal world, the browser should do the right thing here, rather than require special markup to achieve things. There are some open questions: is it ok to use the same margin as the page, or should this be configurable somehow? And how should people opt-int
- 22:26:48 [marcosc]
- o this via intersection observer.
- 22:27:10 [marcosc]
- Issue title is "Ability to have automatic rootMargin for all nested scroll containers"
- 22:28:52 [emilio]

- q+
- 22:29:09 [marcosc]
- SZ: AMP has this problem. But they handle it by having multiple observers... but it's admittedly a bit inelegant. <discussion around root margins>... it's fragile. I'm open to suggestions.
- 22:29:56 [marcosc]
- Emilio: We could maybe use a CSS property? E.g. scroll-margin
- 22:30:24 [marcosc]
- SZ: I have an objection to doing that
- 22:31:08 [marcosc]
- emilio: we could only read this property if intersection observer opted into it?
- 22:31:58 [smfr]
- q+
- 22:32:05 [marcosc]
- ack emilio
- 22:32:34 [marcosc]
- sz: this can be polyfilled by using a stack of intersection observers
- 22:32:59 [smfr]
- q- this was my question
- 22:33:03 [smfr]
- q-
- 22:33:09 [marcosc]
- sp: what wouodl the behavior be when you specify 100% root margin when you have a scrollable container ?
- 22:34:14 [smfr]
- q+
- 22:34:22 [marcosc]
- ack zcorpan
- 22:35:20 [marcosc]
- sz: I'm happy to go along with whatever is generally useful for web developers
- 22:35:44 [marcosc]
- ack smfr
- 22:36:14 [marcosc]
- smfr: my actual question for iframes... what happens with lazy loading with iframes?
- 22:39:28 [marcosc]
- <discussion around iframes, cross-origin iframes and being able to detect when the parent container gets scrolled, and so on... intersection observer being used as a primitive, and algorithms that are internal to the spec, but not exposed to the API>
- 22:39:55 [marcosc]
- sz: the hard part is exposing an public API for this
- 22:40:16 [marcosc]
- smfr: we don't need to expose an API, as we are trying to solve this for lazy loading
- 22:40:52 [marcosc]
- sz: we don't have a concrete proposal right now
- 22:41:33 [marcosc]
- sp: I agree that it's possible without extending the IO API. But I agree that it would be messy because we would need to invalidate a bunch of things.
- 22:41:58 [marcosc]
- sz: we just need a clear + detailed proposal
- 22:42:40 [marcosc]
- Mc: anyone willing to produce the proposal?
- 22:42:48 [marcosc]
- SP: I might get time to do it
- 22:44:07 [marcosc]
- sp: there are a few people who know lazy loading, but I might be able to take it on. If a has opinions about different root margins for different scrollers, please comment in the issue.
