We have some pretty old 3rd party code for our autocomplete UI that has an

improperly declared variable in one of its for loops, which breaks our

autocomplete UI. This didn't cause any problems in previous Review Board

versions, but with our recent JavaScript upgrades we now bundle in our 3rd

party code by importing straight from node_modules, rather than manually

copying it into our tree. This is most likely what exposed the bug. While we

should ultimately move away from this autocomplete code and replace it with

something more modern, for now we'll just patch it. This change fixes the

improperly declared variable.

Manually tested the autocomplete UI.
