bindings.el binds mouse-movement events to `ignore', so I think the same
should be done with the tab bar (and tool bar) mouse-movement events.

But either way, this is probably not a bug in Emacs.  Mark, can you
verify whether or not `track-mouse' is not nil when those spurious
events are generated?  Thanks.
