    patch 8.1.1165: no test for mouse clicks in the terminal tabpage line

    Problem:    No test for mouse clicks in the terminal tabpage line.
    Solution:   Add a test. (Dominique Pelle, closes https://github.com/vim/vim/issues/4247).  Also init
                TabPageIdxs[], in case it's used before a redraw.
