The following .letter::first-letter { color: green; } is causing the problem.

The refcount is 2 instead of 1.

I'm also noticing that the RenderStyle passed to setAnimatableStyle(WTF::PassRefPtr<WebCore::RenderStyle> style)  Line 436    C++
has a refcoutn of 3. 

When the test is working it has a count of 4.
