After opening a <video> in fullscreen, when using integrated volume knob (ie. on keyboard), fullscreen closes and video resumes in window (Ubuntu 10.04/Firefox 4b1)

Reproducible: Always

Steps to Reproduce:
1.Start playing video
2.Open fullscreen by right-clicking and clicking 'Full Screen'
3.Use keyboard volume knob to adjust volume

Actual Results:
Fullscreen closes and returns to window

Expected Results:
Fullscreen remains open with volume adjusted

This bug is specific to Ubuntu, and may have something to do with the volume graphic popping up in GNOME NotifyOSD (the volume widget that appears in the upper-right corner)
