Description

3 years ago
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140715214327

Steps to reproduce:

[Make a cell with class name "social-header"]

I didn't get the bug myself but I'd like to contribute and the developer is too lazy to file a bug report

 23:41 @      ^^^  also i just fixed the weirdest bug in the entire universe
 23:42 @      ^^^  so this one table header cell had a negative width in only firefox 31 for some weiird reason
 23:42 @      ^^^  not in firefox 30, not in any other browser
 23:42 @      ^^^  apparently it was because it had the class name "social-header"
 23:42 @      ^^^  as soon as i changed the class name to "social-header2" it was fixed
 23:42 @      ^^^  like i switched back and forth  several times
 23:43 @      ^^^  and like that was exactly the problem
 23:43 @      ^^^  idk like "social-header" is a magic word in ff 31 or something



Actual results:

[cell with class "social-header" had negative width which is fixed when the class name is changed]


Expected results:

[cell with class "social-header" should not get additional attributes]

Doesn't show any issues for me in Firefox 31, nor does http://mxr.mozilla.org/mozilla-release/search?string=social-header turn up any hits...

Can the other developer (lazy or not...) perhaps provide a testcase? :-)

It might be an add-on that injected a stylesheet into the page.
Given that there are no mxr hits for "social-header" I'm pretty sure this
isn't a bug in Firefox proper.  Feel free to reopen the bug if you have
a testcase that demonstrates the problem.
