Sorry, I'm afraid I still don't understand.

As far as the completion code is concerned, the correct field to use is
the `completion' field assigned by completion-in-region.  In this case,
it's a mistake to pay attention to the underlying widget field.  So why
doesn't it work to give the `completion' overlay a higher priority?

FWIW, increasing the priority of the `completion' overlay does not cause
widget file name completion to fail on GNU/Linux.  Could you try on
Windows?
