Would be a bug, but I can't exactly reproduce it.

I delete the O, then wait 2 seconds (because of 
jit-lock-antiblink-grace, I guess?), and the second block gets fontified 
with font-lock-type-face.

Set jit-lock-antiblink-grace to nil to make this happen faster. Still 
dependent on jit-lock-context-time, though.
