Testcase

STEPS TO REPRODUCE: Load attached testcase from a .xhtml filename.

EXPECTED RESULTS: The two alerts should show the same text.

ACTUAL RESULTS: Two alerts showing different text.

ADDITIONAL INFORMATION: Looks like the innerHTML setter on script/style sets the textContent even in XML, but the getter serializes as XML and ends up escaping things.
