Re: [fxtf-drafts] [filter-effects-2] User feedback: backdrop-filter is way less useful because it requires children to not escape the "backdrop rectangle" (#408)

> And then in that case, the backdrop behind C isn't backdrop-filtered. Is that right?

No. The problem is that C's positioning is completely messed up (by spec, because it limits children to the area of a backdrop'ed parent).

> I don't know of a great workaround for what you're trying to accomplish, other than making the C elements siblings, instead of children, of B, and apply backdrop-filter to C also. Would that not work?

This messes up the markup. You can see this in the code example I coded, I would be forced to move the `<h1>` outside of the `<content>` tag. This really ruins the semantic meaning, therefore I think this backdrop restriction is unreasonable.

I absolutely don't care if C is backdrop-filtered or not - in fact, I would expect it not to be as you suggested, if it is outside the area of B. But that is not the problem, the problem is that it isn't even *allowed* to be outside the area of B.
