Anything else we need to know

The spec still has some open issues but the overall feature design is concrete at this point. Also here is the chrome status entry.

Heads up, we'll have a session on this feature at TPAC on Wednesday. I'll post the exact time next week. Looking forward to see folks interested there!

The breakout session is on September 14 at 3 PST. Details are here including a link to join virtually.

Any results from the TPAC Session on this Topic?

Is there some update about the WebKit’s position on this?

[smfr]

WebKit supports the proposal. We will mark as Support one week from now, pending objections.

Can someone with the permission to update the issue rename the specification in the original post to use "View Transitions"? This will help search for it on https://webkit.org/standards-positions/

[annevk]

Thanks for noticing that @rik. I fixed it.

FYI: In Chromium we're planning to split out some of the pieces of cross-document view transitions to ship separately where it makes sense. Specifically we're currently looking at the pagereveal event.

I want to confirm if WebKit is ok with us using the overall signal for view transitions as the position for those pieces? Maybe a bigger question: should we file a new position request for cross-document view transitions as a whole (i.e. view-transitions API level 2) or is this position sufficient (FWIW Mozilla's reusing the same position for both but thought I'd ask) @nt1m @smfr

It would be good to file new positions for these.
