The problem happens in the Flash players too.

After detaching tab, I see controls only working when page scrolled to 0,0 position... if page is scrolled a bit down, then all events seems translated down too and events not coming to plugin...

And It is reproduced without scroll when open sidebar or Open BookmarksToolbar
In new detached tab, if I open new tab and switch between them,  then it does not help, only reloading of that page helps...
Also found that if non-detached tab was scrolled a bit, then in detached window it works only in that position, scrolling to 0.0 also break that in that case
One more finding, is that if you press right mouse button, then context menu appear in first window!, and scroll position of that first window affecting scroll coordinates of mouse events for detached tab...
Sounds like after detaching tab, plugin retain connected to original window...
Also I can reproduce it on FF6.0 too...
Are you sure that yahoo case is not reproducible on 6.0?
Btw context menu and other problems seems caused by cached NPN_GetValue(NPNetscapeWindow), which is not refreshed on plugin side after moving tab with plugin into new window.
After closing previous window context menu in plugin just stop working at all
