Revert "Debugger: Remove special handling for event dispatcher files"

This reverts commit c75b8f22.

The feature was actually useful. Right now, debugging tends
to stop there, not only in a place people typically don't
expect, because it's not "their" code, but now also with tons
of "Semantic issues" markers which makes the file look
really evil.
