You might want to look into the existing "need a way of showing some
chrome UI over content" bug... I believe the short of it is that it
can sort of be done if the chrome stuff is opaque. If it's not, it
just won't work correctly no matter what you do with it, as things stand.
So how about as-things-change-in-1.9.2?
That depends. roc was going to do this as part of compositor work, but
with process separation it's not clear what the best way forward is.
Or is there another way to
accomplish our goal of showing visual indicators of layout boxes in
content without inserting new content (and hence disturbing the content
we are trying to debug)?
You could use anonymous content (from C++ code). That's more or less
what editor does for its resize handles on images and the like.
It seems like support for chrome-over-content would be a generic feature
of potential interest to many extension developers.
Yes, and to Firefox UI developers too. Like I said, we have a bug on this.
