I don't think that's a workaround.  I think that's what js2 should do,
if (AFAIU) it wants the timer handler be invoked once, after Emacs has
been idle for more than 1 sec.

Btw, in this line:

  (timer-activate-when-idle timer nil)))

I think you can lose the last argument, since it is optional anyway.
