63818 - select boxes in hidden layers still render border

Status: VERIFIED DUPLICATE of bug 58212

(Core :: Layout: Form Controls, defect)

Description

[Kelson]

If you place a form inside a <div>...</div> region, use absolute positioning,
and set its visibility to he hidden, you will see a box around the content of
the drop-down menus created by <select>...</select> elements in the background
color of the select tag.  Normally this isn't noticable, if you have a white
background and you don't mess with the background on the select tag.  I've seen
this on both Windows and Linux.

I've seen this on the PHP home page; when you first go there, there are these
two hollow rectangles over their sidebar, which disappear when you first use the
popups (since they don't position the layers until you trigger one, and that
places them over the text area which has a white background).

I'll also try attaching a test case where I've cut out everything but the part
that causes the problem.

I'm not sure if HTML Form Controls is the right place to send this, but it looks
more specific than Layout.

Verifying as dup of bug 58212 - forms in hidden layer not completely invisible.
