On firefox midi timer stop when tab lost focus (background)

[ftoledo]

Hi i test this great wepapp with firefox. (i known that midi support are experimental)

The app work fine..just only issue..
if i change to another tab, the mpg tab got to background and the midi clock sems to paused
then i return to the mpg tab and get a flooded queue of sequence sounds

I think that is a firefox behavior. i just reporting
maybe the apllicaciton can claim to continue on background i don known.

thanks!!!
