:boris could you consider nominating this for a release note? (Process info)
We could include it in the nightly release notes.

Release Note Request (optional, but appreciated)
[Why is this notable]: We ship a new feature, @starting-style rule. This rule allows us to define the starting style which could be used as the before-change style to start the CSS transitions on the first rendering.
[Affects Firefox for Android]: Yes
[Suggested wording]: Ship @starting-style rule. The style rules inside it are used to establish styles to transition from, if the previous style change event did not establish a before-change style for the element whose styles are being computed.

:boris, looks like your comment 5 should have been added to Bug 1900458. Also, a comment in Bug 1900458 should have been the release note content for this. Pasting here to make clear it up.

Release Note Request (optional, but appreciated)
[Why is this notable]: We ship a new feature, transition-behavior CSS property. This property allows us to create a transition on discrete animated CSS properties.
[Affects Firefox for Android]: Yes
[Suggested wording]: Ship transition-behavior property, which specifies whether transitions will be started or not for discrete properties.
