Alt+Space does not fire in blueprints

When using Alt+Spacebar the space event will not fire. This includes if Alt is added to the event via the details panel. In short the space bar will not fire an event while the Alt key is held down.

1. Open the editor
2. Open the level blueprint
3. Add an input event for the 'SpaceBar' Key
4. Add the ALT key to the event requirement in the details panel for the 'SpaceBar' key event
5. Have the event print a string to the screen
6. Save and compile
7. Play in Editor
8. Press 'ALT' + 'SpaceBar' keys to fire the print string

Result: The event will not fire
Expected: The print string would print to the screen when ALT+Space is pressed
