See upcoming testcase. A xul wizard page ( <wizard xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"></wizard> ) is bleeding out of the iframe where it is contained in. That should not happen. Doesn't happen in 2006-01-25 build, happens in 2006-01-26 build, regression from bug 317375.
Flags: blocking1.9? → blocking1.9+
Fwiw, I just found out that this also can happen on branch builds, just not with this particular testcase. But still, I think this should be fixed, because content in an iframe can overlay from outside its own document this way, which is bad.
There just isn't any code to clip IFRAMEd documents to the IFRAME! This doesn't usually matter for HTML documents, since they usually have a root scroll frame which clips everything. But it does matter for XUL documents and I can probably come up with an HTML testcase using scrolling="no"...

It sounds like this also might fix bug 374327, right?
Maybe ... I'm not sure.
