* bug#51298: 29.0.50; Tab bar buttons won't highlight after the mouse is released outside the tab bar

When moving the mouse pointer over the Tab Bar "new tab" button, the
button appears to have a raised relief highlight.  But after clicking
down on the button and moving the pointer outside the button before
depressing the mouse button to cancel the tab creation, the new tab
button will no longer highlight unless it's clicked again.

The same problem exists when clicking down the tab close button "x".
Patches welcome.

Thanks, please test.  The issue was because f->last_tab_bar_item
wouldn't be cleared when the mouse click was dropped outside the tab
bar.

BTW, I'm attaching another patch that makes the tab bar behave closer to
other programs.  I've explained the behaviour in the commit message.

WDYT?

Subject: [PATCH] Display a tab bar item as sunken when appropriate

When the mouse pointer is pressed on the tab bar, moved out of the tab
bar, and moved back in, it would be more appropriate to behave like
other programs by displaying the item as sunken.

* src/xdisp.c (note_tab_bar_highlight): Display item as sunken if the
mouse pointer returns to the tab bar down.

Thank you for the patches, everything works as it should,
so I pushed both patches.  The second patch didn't apply
cleanly (the difference was in #ifndef HAVE_NS),
so I have to add it manually, but this is not a problem.

This bug report was marked as fixed, but wasn't closed, so I'm doing
that now.  (Skimming the thread, it seems like all issues raised were
addressed.)
