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

[Mark Kennedy]

i'm willing to attempt to debug it myself but not via the -Q route.  i
prefer to focus on where the bad input event stream is being created.
any suggestions about where to put an elisp or C breakpoint to go
after this?
