Using 'Capture Mouse' in a Key Event causes a crash

If you’re responding to a key event, i.e. OnKeyDown, inside a User Widget in blueprint and then attempt to use ‘Capture Mouse’ as part of the event reply, you will crash due to an attempt to dereference a null pointer (specifically a non-existent mouse event).
