Fixes #2437.
Closes #2490.
Due to some inherent limitations, the operation can't access the
on_scroll
function, and so it sets a flag to be consumed on a later event. A better solution might be to give operations access to a Shell, so a message could be triggered manually, but that might not be necessary in this case.
