Source/WebCore:

If box-shadow or text-shadow color is not specified, color defaults to
the value specified in the 'color' property of the element (as specified in W3C
spec).

Test: fast/text/text-shadow-no-default-color.html. Also existing
tests ietestcenter/css3/box-shadow-002 and ietestcenter/css3/box-shadow-003

* css/CSSStyleSelector.cpp:
(WebCore::CSSStyleSelector::collectMatchingRulesForList):

LayoutTests:

Added new test for the case where no color is specified for text
shadow. This test and two others are marked as expected fail pending
rebaseline.

* fast/text/text-shadow-no-default-color.html: Added.
* platform/chromium/test_expectations.txt:
