This is actually an offshoot of bug 126263 - Scrollbars overpaint DIVs. That bug was created due to a customer case where a DHTML menu would appear to paint 'behind' the scrollbar. Take a look at the customer case (http://bugzilla.mozilla.org/attachment.cgi?id=109667&action=view). If you click on "File" in the page, it will open a DHTML menu; then click on "Print" or "Close" to open a submenu. Here you will see that the scrollbar paints over the menu. The problem is that the native scrollbar actually sits on top of the window, whereas the DHTML menus are actually drawn by mozilla directly on the window. The fix in bug 126263 was to remove native scrollbars and have Mozilla create them, with the platforms look and feel. So we need to either back out Mac OS X native scrollbars and revert to Mozilla drawn scrollbars, or find a way to allow the native scrollbars to be overpainted by DIVs.
Adding some other Mac folks. Note that this affects Camino, also.
Created attachment 140116 [details] another testcase Reworked testcase from bug 126263. This one has several HTML elements under a DIV. Only the scrollbars appear above the DIV. Also, this is not an issue under Safari; plus Safari has thinner scrollbars!
this is a dupe of a much older bug, fwiw. we've had this problem for years.
I couldn't find a bug that specifically dealt with this issue, so I opened a new one. If you can find the dup, please let me know. Also, was this also a problem before bug 188254 (Land chimera's form controls on the trunk) was landed?
this started when we landed native scrollbars in mac mozilla, which was easily a year and a half ago, if not longer. i think this can be duped to 191265, no?
yeah, that looks to be the correct dup. i didn't read the whole bug. thanks. dup -> bug 191265 *** This bug has been marked as a duplicate of 191265 ***
