patch 9.2.0397: tabpanel: double-click opens a new tab
Problem: tabpanel: double-click opens a new tab page
Solution: Do not create a new tab page when using a double click
(Yasuhiro Matsumoto).
The tabpanel click handler inherited the tabline behavior where a
double-click opens a new, empty tab page. Unlike the tabline, the
tabpanel has no "empty area": every row maps to some tab, so this
fires on any double-click in the tabpanel and can generate stray
empty tabs. The behavior is also not documented for the tabpanel.
Skip the new-tab branch when the click originated in the tabpanel
and fall through to the regular tab-switch path instead. The
tabline behavior is unchanged.

+A left click on a row in the tabpanel selects the tab page that the row
