Rather than hooking is there a way to force a particular location?

Possibly. Again, this is just existing code moved here to be re-used from either
the browser or utility process.

I would assume that the intention is that 99% of the time, allowing the built-in
machinery to act and remember the previous location is correct. And so we just
need to detect the 1% of the time that this gives bad results.
