Generally we try to match the name of the module with the IDL suffix.  For
example, you could change the directory to be called "midi" or the IDL file to
be called DOMWindowWebMIDI.  Either is fine, but this mismatch is slightly out
of the norm.

I'd recommend changing the .idl to DOMWindowWebMIDI.idl

Done.
