Sure.  The Gecko behavior is to not run the inline script until the 
stylesheets have loaded, just like webkit (and Gecko) does for 
non-inline scripts.

Any inline script that asks for layout information is affected, right? 
Good question on how much this is a problem in practice.  I don't have 
data on that....
