205942 - Alt+Down shows dropdown for Combobox in wrong location

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect)

Description

[jhp (no longer active)]

If using Alt+Down to drop down a combobox, the dropdown will overlay the
combobox element.  However, when using F4 to drop it down, the dropdown
correctly appears below the combobox.  After using F4, Alt+Down now works
correctly;  it only fails the first time.

After a bit of experimentation, I have observed that
1) for some drop-downs, what the original bug description says applies
2) for some drop-downs, the drop-down displays somewhere completely different
   (e.g. the "OS" drop-down on this page displays about 1/4 of the screen's
   height further down than it should)
3) for most drop-downs, it doesn't display at all (it might be displaying
   entirely off-screen).

It's because of (3) that I opened Bug 221846, which is probably a duplicate of
this then.

May be related to bug 211846.

Very strange that F4 works better than Alt+Down. Why would they follow different
codepaths?
