It's not entirely clear to me what "this behavior" you're referring to,
but yes, of course it's going to be proportional to the number of menu
entries that need to be populated.

I don't understand either and that's not normal behavior. I imagine the
debugger would be better at explaining this than me.

Given that I can't reproduce your problem, it's hard to explain what you
might do differently to avoid it. It seems to me the problem is the
fact it's being called for every element of the tree and not just for
the one selected element.
