Bug 81859 – Chromium: Should enable -webkit-image-set

• Component: CSS
• Status: RESOLVED FIXED

[Beth Dakin]

https://bugs.webkit.org/show_bug.cgi?id=80322 adds a new CSS property called -webkit-image-set. Since the implementation is currently incomplete, ports have to opt-in. Chrome should decide when to opt in.

Why do we fail these subtests?

It seems we do this for all the chromium tests which use toString to verify the class prototype and constructor since chromium always returns Object and Function for these respectively. For example for the prototype:  
egrep --exclude-dir=".svn" -r "jsWrapperClass\(.*.__proto__\) should be [A-Za-z]*\. Was Object\." . |wc -l

Interesting.  I wonder when that started.

Relanded in http://trac.webkit.org/changeset/114163. The features.gypi change required clobbering the windows chromium bots. I don't think I have permission to close the issue.

Robert, if you ask eseidel in #webkit, he should be able to give you the EditBugs permission.
