- Resolved: Percents that are resolved against numbers do that at parse time (Issue #9395: Resolve `percentage` representing `number` or `angle` at parse time)
- Resolved: Drop mix() from Values 4 (Issue #9343: Abandon mix()?)

- The group wants to make sure that if we make changes in issue #8915 (Blocking effects of timeline-scope) it wouldn’t lead to problems that would make containment less impactful. Discussion will return to the issue for more investigation.

- The next F2F will be Feb 12-14 in Mountain View CA. Group members are asked to add to the wiki if they will be attending.

- Zoom will be specified in the Viewport spec
- Resolved: getComputedStyle() returns unzoomed value so that it round-trips (Issue #9398: Zoom and CSSOM)
- Resolved: APIs that return bounding boxes such as getClientRects and getBoundingClientRect and IntersectionObserver return values in page-global px unit coords (Issue #9398)
- Resolved: font-size is not special wrt zoom (Issue #9397: Zoom and inheritance)
- Resolved: All computed absolute lengths are zoomed when inheriting (Issue #9397)
- Resolved: If overflow:scroll is set on the root element (not propagated from body), account for the default scrollbar width in the size of vw. Also take scrollbar-gutter (and scrollbar-width, the property with “normal” and “thin”?) into account on the root. Ignore all of these in MQs. And also ignore all of these when using vw/vh units on the root element, if necessary (Issue #6026: Use of 100vw is causing pointless horizontal scrollbars on some websites)

- Resolved: Accept some form of masonry slack property; exact algorithm TBD; exact name TBD (Issue #9328: Reordering threshold)
- Resolved: Though it was clear how Masonry would handle `auto-repeat` accepting intrinsic sizes, it was more uncertain if it could work in Grid. Discussion will continue in issue #9321 (Allow `auto-repeat` (i.e. repeat(auto-fill|auto-fit, …)) to accept intrinsic sizes) to understand further how it could be added to Grid.
- Resolved: Restore text simplifying out single-argument min/max functions (Issue #9559: Simplification algorithm should possibly return single child for min/max)

- Resolved: type can accept any idents, except ‘none’ or ‘-ua-‘ prefixes (Issue #9534: Resolve on descriptor/parameter names)
- Resolved: at-rule is @view-transition, descriptors are ‘navigation’ and ‘type’, ‘navigation’ grammar is “auto | none” (‘type’ grammar already resolved) (Issue #9534)
- Resolved: A startVT() called on the new page will force-finish an MPA VT even if a frame hasn’t painted yet. (startVT() late in the old page is still undefined) (Issue #9512: Starting a same-doc view transition while a cross-doc view transition is pending)
- Resolved: startVT() on the old doc is ignored if there’s an active MPA VT running, but its callbacks are still dispatched (Issue #9512)
