could this add event listeners more than once (meaning the extension could
reload 2+ times for 1 click)?

  terminatedReload.onclick = function() { ... };

would ensure this doesn't happen...

[Devlin, 2014/09/19 21:30:08]

I'm pretty sure it's not a risk - this is all in createNode_(), which clones a
new node, and this is the only place we set the listeners.  But I suppose it
can't hurt to be safe?
