Issue: In WebKit 619.1, MutationEvent was properly handled and overridden, so casting to it worked as expected. In newer WebKit versions (like the one embedded in current JavaFX), MutationEvent is deprecated, and the actual event dispatched is just a generic DOM Event. Solution: restore the old style mutation event support, which will cause the returned events to again be instances of MutationEvent.
