Bug 15168 – REGRESSION: [Tiger only] Select pop-up menus are drawn split on bugzilla.mozilla.org

• Component: Forms
• Status: RESOLVED WONTFIX

[David Kilzer (:ddkilzer)]

* SUMMARY
Certain pages on http://bugzilla.mozilla.org/ cause select pop-up menus to be drawn split.

* STEPS TO REPRODUCE
1. Launch Safari/WebKit.
2. Go to URL: https://bugzilla.mozilla.org/enter_bug.cgi?product=Bugzilla
3. Scroll down to "Flags" area.

* EXPECTED RESULTS
Select pop-up menus should be drawn normally.

* ACTUAL RESULTS
Select pop-up menus are drawn "split".

* REGRESSION
This is a regression from shipping Safari 2.0.4 (419.3) with original WebKit on Mac OS X 10.4.10 (8R218).

Tested with a local debug build of WebKit r25458 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).

Partial reduction

> Partial reduction

NOTE: I added a border to the outer table during the reduction, and it became part of the reduction.  Removing it prevents the bug from occurring, although changing border="0" and cellpadding="1" will preserve but buggy behavior.

The border="1" attribute on the outer table may also have lead me to remove CSS that was contributing to the bug without the border being present.

In any case, this issue seems to be linked to a number of different factors all contributing to create the bug.

I cannot reproduce this with r25449 - is the regression that recent? Or is there something else about system configuration that contributes to this?

I'm also using Safari 3 Public Beta v.3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).

No, the regression occurred when the "native" pop-up menus were implemented.

I do have the "Press Tab to highlight each item on a webpage" checked.

I also have the "All Controls" radio button selected in the "Keyboard Shortcuts" tabs in the "Keyboard & Mouse" system pref pane.

I also have "Enable access for assistive devices" checked in the "Universal Access" system pref pane.

Not sure if any of those make a difference or not.

Using the same software with WebKit Nightly r25449, I can reproduce the issue with the original URL and the reduced test case.

I figured it out.  It has to do with the size of the browser window.  Shrink your window horizontally until you see the gap appear in the pop-up menus.

I cannot reproduce the bug with Safari 3.0.4 nor with TOT on 10.5.2.

I can still reproduce this with r30353 and Safari 3.0.4 on 10.4.11.  You MUST resize the browser window so that its width is less than the table.  Also reproduces with stock WebKit and Safari 3.0.4 on 10.4.11.

I did! I did!

Thanks for testing. I will try on 10.4.11.

Still occurs with Safari 4 Public Beta on Tiger 10.4.11 (8S165).

Tiger is no longer supported.
