Some tests in style-with-shadow-pseudo-element.html and
style-with-deep-combinator.html did check if a style rule
in a shadow tree can be applied to its sibling shadow tree(s),
which is against the current spec.

I will add some test *against* such case, that a style rule
doesn't apply to its sibling shadow tree, along with the fix for
bug 355674 later.

BUG=355674
TEST=pass layout tests.
