Documentation problems aside, you can't usefully define which events
will be considered as input and which won't, in a way that would DTRT
for everyone.  The decision is specific to the application, and
while-no-input cannot know that.

It could be that this particular event can be filtered out, but that's
just the top of the iceberg.  There are way too many different events
flowing into Emacs on a typical modern system, keyboard being just a
small part of that.
