[FIXED] [OSX] Keyboard shortcuts don't follow active window

[xlii]

When there is more than one window, keyboard shortcuts work only on the main Geometry one, even if the other one is active.

How to reproduce:
1. Add cube
2. Select and choose UV Mapping
3. Select edge, vertex, face, whatever in UV Window
4. Press Space

Desired effect:
- UV Window selection cleared

Effect:
- Main Geometry window geometry cleared

EDIT:
- I verified and the problems doesn't exist on Windows
- Version I'm referring to is 2.0.5
