Re: [csswg-drafts] [css-2026][css-transitions-2] Add `transition-behavior`, `@starting-style`, and `CSSStartingStyleRule` to Safe to Release exceptions (#12778)

The CSS Working Group just discussed ``[css-2026][css-transitions-2] Add `transition-behavior`, `@starting-style`, and `CSSStartingStyleRule` to Safe to Release exceptions``, and agreed to the following:

* `ACTION: Hassle dbaron about republishing and about whether this entire spec should go into the Snapshot or only parts ofit.`

<details><summary>The full IRC log of that discussion</summary>
&lt;fantasai> SebastianZ: Proposed to add transition-behavior, @starting-style, and CSSStartingStyleRule<br>
&lt;fantasai> SebastianZ: They were already part of Interop 2024 and Interop support is 90%<br>
&lt;fantasai> SebastianZ: Some issues but non on the spec<br>
&lt;astearns> ack fantasai<br>
&lt;astearns> ack florian<br>
&lt;Zakim> florian, you wanted to cycle back to ui-4<br>
&lt;fantasai> fantasai: Hasn't been republished in awhile, and also is there any reason not to include the whole spec?<br>
&lt;fantasai> astearns: Maybe add to Safe to Release first, and then pull up whole spec later if appropriate<br>
&lt;fantasai> fantasai: Let's not reference old things<br>
&lt;fantasai> astearns: So table this and then republish and then revisit to see if we can add the whole spec or just some exceptions<br>
&lt;fantasai> fantasai: Sounds good. Let's hassle David.<br>
&lt;fantasai> ACTION: Hassle dbaron about republishing and about whether this entire spec should go into the Snapshot or only parts ofit.<br>
