Reviewed by Sam Weinig.

* LayoutTests/fast/borders/border-image-legacy.html: Expect initial values instead of the
keyword "initial" for specified style.

* LayoutTests/imported/w3c/web-platform-tests/css/css-backgrounds/parsing/border-image-shorthand.sub-expected.txt:
Expect PASS.
* LayoutTests/platform/glib/imported/w3c/web-platform-tests/css/css-backgrounds/parsing/border-image-shorthand.sub-expected.txt:
Ditto.

* Source/WebCore/css/StyleProperties.cpp:
(WebCore::StyleProperties::borderImagePropertyValue const): Change the code that checks for
implicit values to not require use of the initial keyword.

* Source/WebCore/css/parser/CSSPropertyParser.cpp:
(WebCore::CSSPropertyParser::consumeBorderImage): Set initial values using the actual values
rather than the initial keyword.
