Yes, and the problem is, we don't really know the answer. Someone at
some point made it ignore some events, and also made it conditional on
whether toolkit scrollbars are or aren't using. We don't understand
why, and we now want to add more ignored events to the list, which
will change the (partially unknown) behavior even more.

A new flag might be a good idea, indeed, but (a) I'd need to see a
patch to have a clear idea what you mean, and (b) the application of
that flag should be dependent on that variable exposed to Lisp, so
that if problems happen, we can ask users to flip the variable and see
if the problems go away.

No, it must be a separately controlled behavior, see above.

In general, yes. But isn't that precisely what you suggest we do
here? ;-)
