According to the Emacs manual, major-mode hooks are run as the *last* step of
initialisation, so I'm not sure why this isn't working for you.  I have an
idea that may or may not be helpful: if highlight-symbol can run hooks, have
it detect the major mode of the current buffer and disable itself.  If that
doesn't work, then, as a rather crude hack, you could have your js2-mode hook
run after a short delay, but that would be unreliable, as it's time dependent.
