I can click & drag to select text while the pointer is locked on this page: http://people.mozilla.com/~cpearce/pointerlock-position.html This shouldn't be possible while the pointer is locked. STR: 1. Load http://people.mozilla.com/~cpearce/pointerlock-position.html 2. Press 'F' key to enter fullscreen mode. Approve fullscreen. 3. Press 'P' to key to enter pointerlock. 4. Click the mouse and drag, note that a selection highlight appears around some of the text.

We want to prevent only selection happening using mouse, not selection using keyboard.
