I recommend to either `@Ignore` this test or else reset it to an empty style sheet (which is effectively what it will be for `javafx.graphics` tests, since the platform initialization code that sets up the default stylesheet is never called for these tests).

I've decided to reset the UA stylesheet to an empty stylesheet.
