265614 - width of dropdown menus on web forms don't account for scrollbar

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect)

Description

[Chris Gordon]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.7.3) Gecko/20040913 Firefox/0.10.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.7.3) Gecko/20040913 Firefox/0.10.1

A great feature of Firefox is that when viewing a dropdown menu with a fixed
width specified by style="width:nnpx", when clicking on the menu to expand it
the dropdown items will adjust accordingly if any of the items are too long to
fit within the specified width. If there are a lot of items in the list it will,
naturally, add a scrollbar, however the calculation for the width doesn't take
into account the newly added scrollbar and the text gets cut off.

Reproducible: Always
Steps to Reproduce:



Expected Results:  
I would expect to be able to see the whole text of each line, and if a scrollbar
was required it will adjust the width appropriately

Here's a link to a sample: <a

off here is "Relay Fundamentals Course". (I can't give a link to the site this
is from as it's a private site)

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.

Yes I just confirmed this bug still appears. I've verified this in 1.0.7 on both
Windows and Mac. Attached is a sample. Note the 2nd last item is cut off by the
scrollbar.
