277471 - CSS :focus rule causes select field to not drop down list

Status: RESOLVED DUPLICATE of bug 163503

(Core :: Layout: Form Controls, defect)

Description

[Mattias Thorslund]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a6) Gecko/20050107 Firefox/1.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a6) Gecko/20050107 Firefox/1.0+

When I use a ":focus" rule on a select field, the behavior changes. Normally,
clicking on a select field (a.k.a. combo box, drop list) will cause the list to
drop down immediately. With a :focus style, the first click will only focus and
not drop down the list. On the third click, it drops down. This happens only
when the page has just been loaded.

Reproducible: Always

Steps to Reproduce:
1. Load the test page, http://www.thorslund.us/focustest.html
2. Click on the second select field.

Alternatively, make your own test page with the following:

Style: 
		select {
			background-color: #dddddd;
		}
		.withfocus:focus {
			background-color: #ccddcc;
			border-color: #88dd88;
		} 

...and a Select field:
	<select class="withfocus" name="field2">
		<option>one</option>
		<option>two</option>
	</select>
Actual Results:  
It will focus on the field, applying the :focus style, but it won't drop down
the list of option elements. To see the list, I have to click two more times. 

After the list has been displayed, the select field works as expected. To see
the problem again, you must reload the page.

Expected Results:  
It should apply the :focus style AND drop down the list, on the first click.

Tried this on WinXP also and there is no problem - it will focus and display the
list on the first click. So it seems the bug is only in the Linux version.  

Using the latest build of Firefox (07-Jan-2005) on Linux Mandrake 10.1.

Sorry for entering a duplicate.  I did try to search for it before filing it,
however, but couldn't find any matches for :focus and select.  Maybe the search
function needs to be improved so that it supports a klutz like myself :-)
