<pre>ASSERTION FAILED: columnCount in WebCore::CSSParser::parseGridTemplateAreasRow
https://bugs.webkit.org/show_bug.cgi?id=136945
Reviewed by Sergio Villar Senin.
Source/WebCore:
Checking out whether the grid-template-areas value contains a white-space only
string, which is not valid as it does not produce a cell token.
Test: fast/css-grid-layout/grid-template-areas-empty-string-crash.html
* css/CSSParser.cpp:
(WebCore::CSSParser::parseGridTemplateAreasRow):
LayoutTests:
Testing the different types of white-space only strings for the grid-template-areas
property, which is not valid as it does not produce a cell token.
* fast/css-grid-layout/grid-template-areas-empty-string-crash-expected.txt: Added.
