Comment (by cypherpunks):

 > My guess is that the second execution happens somehow in this new window
 context which is not properly initialized yet.

 I think second execution happens for the same menu popup as for first
 click. Browser keeps menu while context was destroyed or should be
 destroyed, race condition is about order of destroy for menu popup vs
 tabs. Or no races even, browser destroys context of window first while
 menu exist till the end. Bug is about speedness of user vs. speed of code
 execution (possible depends jit?).
