This is because clicking the middle button during isearch calls
isearch-mouse-2, which calls the usual mouse-yank-primary, which calls
isearch-done to finish isearch. Problem is, it let-binds
overriding-terminal-local-map around this call, which counteracts
isearch-done setting this variable to nil. The end result is having quit
isearch, but with the overriding map still in place.

I have attached a simple patch below. Eli, if it's satisfactory, would
you commit it for me?
