Status: RESOLVED FIXED

(Core :: Layout: Tables, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7.8) Gecko/20050517 Firefox/1.0.4 (Debian package 1.0.4-2)

If I set up a text menu in a colored HTML table completely configured via CSS
and define a hover,when the mouse leaves the link, the normal link will not be
correctly restored. This happens only with the longest entry in the menu. If you
move the mouse quickly, the white bar at the end of the longest entry, might
even extend over larger parts of the table.

Reproducible: Always

Steps to Reproduce:
1.Move mouse over the longest menu link
2.Move away from the longest link

Actual Results:  
About the last letter of the link, you'd moved the mouse over will be covered by
a vertical white bar. If you move the mouse quickly, the bar will even extend to
the neighbouring columns.

Expected Results:  
The link should be restored correctly in the same color as was selected as
background color for the table.

This problem also aoccurs in recent versions of Firefox for Windows and at least
with Netscape 7. Seems to be a problem that's common for all browsers running on
the Mozilla engine.

This test case sets up a menu just as described in the report.

Looks like an interaction between border-width, frame, and cellpadding.

Attachment: minimal testcase

Hmm... for some reason the bug appears when the rules attribute is set to
anything, even "none" (the default), but not when rules is unspecified.

Forget comment 6, sorry. "minimal testcase" works,
"test case" and my "testcase 3" fails.
