203748 - Cannot scroll HTML SELECT with width style using thumb

Status: RESOLVED DUPLICATE of bug 201797

(Core :: Layout: Form Controls, defect)

Description

[Stephen Moehle]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20030428
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20030428

An HTML SELECT control cannot be scrolled using the mouse and the thumb of the
SELECT's scrollbar if it has a width style as in:

<select name="B" style="width: 2.4in;">

The thumb highlights when clicked on, but it will not move up or down and will
not scroll the contents of the SELECT.  Remove the style, and it works.  This is
a regression within the last couple of weeks.

Tested with Mozilla trunk 2003-04-28-15 on Linux and 2003-04-28-08 on Windows 2000.

Reproducible: Always

I've been trying to track down when this problem was introduced. Going back to
build 2003042105 the test case causes a crash when the scroll bar is clicked.
Build 2003042208 gives the same behaviour as current nightlies. The checkins in
this period are given by: 

http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=SeaMonkeyAll&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=04%2F21%2F2003+00%3A00%3A00&maxdate=04%2F22%2F2003+23%3A59%3A59&cvsroot=%2Fcvsroot

The ones that stand out as related to scrolling from this list are bug 201767
and bug 201624, but I can't see which if either might have fixed the crash (and
hence potentially have lead to this bug).

This seems to be fixed in the latest nightly build - 2003050610 on Windows XP Pro.

Comment 6

[Stephen Moehle]

You are right.  This is fixed with 2003-05-07-04 trunk on WinXP.  Marking as such.
