 # ====== Oilpan-only failures from here ======
 # Most of these actually cause the tests to report success, rather than
 # failure. Expected outputs will be adjusted for the better once Oilpan
 # has been well and truly enabled always.
 
 # With Oilpan, the parent pointer in the CSSRule hierarchy is
 # strong. This is the intended behavior.

This is the test that was, originally intended, to test ligature formation in
combination with 'x'/'y' positioning. It's much weaker without the custom font
though.
