SUMMARY Middle click inside Tmux works sometimes, but sometimes not. I think this is a Konsole bug because it is normal in xterm. STEPS TO REPRODUCE 0: Open Konsole and start Tmux inside it. 1: Run `tmux bind-key -n MouseUp2Pane pipe -I -t= 'echo -n test'`. 2: Middle click multiple times (maybe 20 times). OBSERVED RESULT For some clicks, a `test` is inserted. For some others, nothing happens. I personally tried 20 times, and it worked for 17 times. If one starts a `nano` and try middle-clicking there, the frequency that it works seems to be smaller. I personally tried 20 times, and it worked for 15 times. EXPECTED RESULT It should work all the time, i.e., for every middle click, a `test` should be inserted.

This problem does not restrict to middle click. Right click also has this problem, as you do `tmux bind-key -n MouseUp3Pane pipe -I -t= 'echo -n test'`.
