Thanks for the patch. I looked into this, and tunnels should have been cleaned
up when VNC disconnected like it has always worked. Turns out some cleanup
code I added was cleaning up the VNC widget too early, preventing the
disconnect signal from being delivered.

I've pushed a different patch that fixes the issue here and should be a simple
backport. More info also in the description:
