442857 - Table column sizing is sometimes dependent on nearby tags, style changes etc

Status: RESOLVED WORKSFORME

(Core :: Layout: Tables, defect)

Description

[Wladimir Palant]

Attachment: Testcase

Testcase attached - minimized from a cPanel page. The script at the bottom changes the DOM slightly when the page loads. Note how the first column of the table gets zero width for no obvious reason. Note also that any change in style (e.g. by selecting "No Style" and then "Basic Page Style" in the View / Page Style menu, any call on nsIStyleSheetService has the same effect) makes the *second* column get zero width. Both effects disappear if you remove any of the other tags (like h1 or ul) from the document - why do those change the table at all?

I see this in Firefox 3.0, not in Firefox 2.0.0.14 however.

A number of checkins touch layout but I don't see any obvious cause for this issue.

I am the original reporter of this bug. I also have two other filters besides "EasyList" installed: ABP Tracking Filter and EasyElement. I don't know if that would affect this bug any, but I want to make sure I'm not sending everyone on a wild goose chase.

John, this bug can be reproduced entirely without Adblock Plus - so filters don't matter.

WORKSFORME in Firefox 3.6.3, I guess this issue has been resolved.
