Alt+Shift+F10 and some others not working (not captured)

Base case
=========

Step:
- Turn Num Lock on.
- Press Alt+Shift+F10 in an IDE that has that shortcut set.

Exptected: works as expected.

Actual: does nothing.

Testing with Gnome Settings
===========================

Alt+Shift+F10 can be added as a shortcut in Keyboard Shortcuts in Gnome Settings, and it works.

Testing with `xev`
==================

When Num Lock is on, pressing Alt+Shift+F10 doesn't print any F10 press/release events.
