I'm not seeing any difference between the patched and the unpatched
behavior.  Could you give me a specific set of instructions to test,
inclding any mouse or replot/refresh commands?

Both the patched and unpatched code versions lose track of the "reverse"
setting after an unzoom operation using the "u" hotkey.
