87159 - List boxes do not get focus when scrolled via mouse

Status: RESOLVED WORKSFORME

(Core :: Layout: Form Controls, defect, P1)

Description

[Brian]

1.  Go to http://buzilla.mozilla.org/enter_bug.cgi?product=Browser
2.  Focus on a non-listbox control, e.g. the Description textarea.
3.  Scroll the Component list box via its scroll bar.
4.  Focus stays with the Description box, so up/down arrows don't move the
selection in the list box.

I suppose this has something to do with the value of the size attribute in the 
"select " element.

Look at the attached testcase.
There are 2 scenarios:-
scenario 1:
===========
there is a list box with the "size" attribute equal to the number of options.
actual: 
when i click on the scrollbar side of the list box, i am able to use the up-down 
arrows from the keyboard to make my selection. The focus is on the list box.

scenario 2:
===========
there is a list box with the "size" attribute less than equal to the number of 
options. 
actual:
if i click on the scrollbar side of the list box, the focus does not come on the 
list box. Whereas, if i click on the inside of the list box, it gets the focus.
expected:
The list box should get the focus even if i click on it's scrollbar side.

changing OS to *all*

This is probably bug 9086, but leaving open just in case the fix for 9086
doesn't fix this case.
