228054 - SELECT element inoperable when attaching CSS :hover selector

Status: VERIFIED DUPLICATE of bug 163503

(Core :: Layout: Form Controls, defect)

Description

[Didier Moens]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6b) Gecko/20031208
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6b) Gecko/20031208

When creating a CSS select:hover rule, the dropdown SELECT element ceases to
function : it does not react to either mouse clicks or keyboard events, hence
rendering data entry impossible.



Reproducible: Always

Steps to Reproduce:
Add a non-empty CSS :hover selector rule to a SELECT element.
Actual Results:  
SELECT element cannot be operated anymore.

Expected Results:  
Mouse and/or keyboard event dropdown and select.



As I did not experience this in Mozilla 1.4 and prior versions, I consider this
a regression ; Mozilla 1.5 was not tested.

The erroneous behaviour occurs with both the
mozilla-i686-pc-linux-gnu-1.6b.tar.gz release and with a fresh custom compiled
Mozilla 1.6 from source tarball.


Considering that :

1. this is a regression, and 

2. all our web applications use the :hover selector behaviour to give visual
feedback on active form fields, hence this bug preventing our clients to upgrade
to 1.6,

I took the liberty to set severity = 'major'.
