Popups hidden by admin block

I can only reproduce this with the Overlay enabled and dragging TinyMCE's inlined popus - as in they having no separate windows - all the way up under the toolbar manually, or having a very long form and scrolling until they go up there.

The Overlay moves the toolbar to the very top of pretty much anything you throw at it.
I don't know how to change TinyMCE's styling so its popups get placed ontop of the toolbar, unless I restyle the toolbar so it goes below the Overlay too.

We have some code in the latest versions of Wysiwyg which hides admin toolbars created by known modules (core and admin_menu) while editors are in fullscreen mode and the Overlay is active. I don't think we can automatically determine when to hide the admin toolbars, to allow for dialogs, when the editors aren't in fullscreen mode since we can't determine when dialogs are shown. Doing so would also mean the document would jump up each time the toolbar is hidden and jump back down when they are revealed again.

I can't find a good way to deal with this in Wysiwyg itself. We can't change the editor's own styling so we'd have to add overrides to Wysiwyg's stylesheets, but I'm not sure what to override because I find the issue difficult to reproduce without having a screen small enough to not fit the dialogs, at which point no editor would be very practical to use.

I'm sorry, but I have no choice but to mark this a "won't fix" for now. If you have examples of where this can be reproduced without very small screens or suggestions or even working solutions for a fix, I'd be glad to hear it.
