This shows that the button and key is actually recognized and not intercepted elsewhere.
It appears that the configuration for anything related to the left mouse button is ignored (using the application's defaults instead). Any other button (as shown in "Relevant Configuration" above) works just as expected. The same left mouse button lines starts working when s/Left/Middle/ or any other valid mouse button.
I even tried disabling those buttons beforehand by adding action = "None" for them, but it did not do anything either.
Is this expected behavior? If so, why?
