Re: [csswg-drafts] [css-anchor-position-1] position-visibility: anchors-visible should be clear about when is visibility determined (#12732)

Some folks use `transition: all 1s`, so this change will not be backwards compatible. Existing sites might experience a new unexpected transition as a result, not to mention the unexpected stacking context change side effect.

I generally don't think this is a reasonable side effect to expect from `transition-property: all` to have their element suddenly fade in and out. It feels like a magical quirk.
