I'd be worried if this is the correct behavior.   If that is what the spec says
then maybe it should be fixed / clarified. A more realistic scenario then the
test case I provided is if there is applicationCache logic in the external
javascript file. For instance a simple library that interacts with the
applicationCache in order to provide users with a custom user interface (as
6.9.4.4 mentions a default User Agent Interface) indicating what is happening.

In this case I wouldn't want the applicationCache's checking event to fire
before that external script, which would contain handlers for these types of
events, is downloaded!
