bug#51794: 29.0.50; invalid input events generated from a mouse click for the tab bar

[Mark Kennedy <mark.t.kennedy@gmail.com>]

bug fix #50993 is the bug.  it made make_lispy_position skip setting
posn to the tab_bar if track_mouse is non-nil.  why track_mouse is nil
for some frames and not for others i didn't look into.
thoughts/comments?
