Merge 135578 - REGRESSION (r128633): td changes size during re-layout of table although it shouldn't
https://bugs.webkit.org/show_bug.cgi?id=102802
Patch by Julian Pastarmov <[email protected]> on 2012-11-23
Reviewed by Ojan Vafai.
Source/WebCore:
The bug was caused by incorrectly rewriting a nested condition which caused the else
clause to trigger in wrong cases.
Test: fast/table/nested-tables-with-div-offset.html
* rendering/RenderBox.cpp:
(WebCore::RenderBox::computePercentageLogicalHeight):
Reverted wrong combination of nested if statements.
LayoutTests:
This test checks that table layout of some nested tables in quirks mode is computed correctly.
* fast/table/nested-tables-with-div-offset-expected.txt: Added.
* fast/table/nested-tables-with-div-offset.html: Added.
