Bug 7296 enabled exceptions for invalid CSS values being set via DOM.

This has caused a problem with Mozilla-only cursors: Mozilla (of course)
supports those, and IE has a quirk that lets it handle them without raising an
exception. In IE, "-moz-grab" is treated as "url(-moz-grab)". Moreover,
"url(foobar), -moz-grab" is also parsed "successfully" somehow.

So, WebKit is the odd one raising an exception now. This can be fixed by adding
support for those cursors (bug 8988) or by implementing an IE-style parsing
quirk.
