The CSS WG decided to remove the fallback background color feature from css3-backgrounds (and potentially add an equivalent later using a new value type, e.g., an image() function that takes fallback).

We should remove the implementation that was added in bug 322475.

:(

This seems like a pretty good feature anyhow, perhaps just change it to a -moz prefixed solution for now?

I think some ui features rely on this, cc'ing dao to weigh in here.
This feature is not in 3.5; I don't think we've done much UI development that's for post-3.5-only.  Furthermore, there are much nicer ways to have syntax for the same feature.
Yeah, we haven't used this yet.

I don't think any documentation is needed here, since we removed a feature that we never shipped in the first place (so that we wouldn't ship it).
The implementation in bug 322475 was documented, so I need to make sure the background color fallback support isn't part of what got documented. Hence the addition of the doc-needed note here.
OK, after some reviewing of the docs, this doesn't in fact require any tweaks to the docs, so removing the tag.
