[css-anchor-positioning-1] implied auto try blocks are confusing

[fantasai]

Example 9 in the spec https://www.w3.org/TR/css-anchor-position/#fallback-automatic shows off a "feature" that's super confusing to understand. The code doesn't make sense when you look at it. I understand @xiaochengh's suggestion of having specifying a fallback strategy, but having an implied @try blocks generated as "mirror images" of an existing try block because it happens to have an auto keyword in one particularly magic place is too much magic.

We've also addressed that in #9196's resolution: we'll get rid of auto and auto-same completely and use a standalone property to generate auto fallbacks.

So I don't think we have any work to do in this issue. Can we close it?
