Test case

When the width of a TD is restricted in a fixed-layout table (table-layout:fixed), the TD's reported scrollWidth may be incorrect.

Please see the attached test case. I have tested Firefox 20.0, Firefox ESR 17.0.5, and Firefox 12.0 and found that the scrollWidth of `theTD' is 98. In Firefox Beta 21.0, Firefox Aurora 22.0a2 (2013-04-12), Chrome 26.0.1410.65, Safari 6.0.3, and IE 9, the scrollWidth is correct, ~293.

I used mozregression and found:

Last bad nightly (contains this issue): 2013-01-29
First good nightly (fixed): 2013-01-30


This range includes the patch for Bug 833542, and I think that the 833542 patch also fixed this bug.

So I'm confused.  If this is fixed... what's this bug about, exactly?
Comment 2 Daniel Trebbien 2013-04-12 09:00:07 PDT
This is fixed, yes. I wasn't sure if another test case should be created specifically for this bug given that the 833542 patch seems to have fixed this bug unintentionally.
Comment 3 Boris Zbarsky [:bz] 2013-04-12 09:02:32 PDT
Ah, I see.

Proposed Mochitest test case - dom/tests/mochitest/general/test_bug861217.html

Attached is my proposed Mochitest test file. When I run the test file in a build of Firefox @ 129356:4420f27742c7, I get the following result:

Passed: 32
Failed: 0
Todo: 0

Yeah, much better.  ;)  Now you just want to request review.  But since I'm here anyway, r=me, and thank you!

Awesome! Thank you!

I guess this can be marked "FIXED"?

It will be once it's merged over to mozilla-central.
