There are… a lot of proposals, but you don't need to rank them all. Skim through the list, and find the few you really care about.

This is an experiment, so we're also interested in feedback on the app itself, and things we can improve for next year.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.

View Transitions are enabled by default in Firefox Nightly, so they're on their way to stable. Give it a test with your current transitions, and give me a shout if anything doesn't look right.

thanks for the bug, we'll look into it

Can you file a bug in bugzilla.mozilla.org ? We'll then run some investigations to check what's happening.
Is the issue only visible when Responsive Design Mode is enabled? Or is this simply related to viewport size?

that's tracked in bugzilla.mozilla.org/show_bug.cgi...

but I don't think there's any short term plan supporting them
(there's an early implementation behind `layout.css.style-queries.enabled` that you can turn on in about:config)
