patch 9.2.0169: assertion failure in syn_id2attr()

Problem: assertion failure in syn_id2attr()
(@julio-b, after v9.2.0093)
Solution: Set tp_curwin to a valid window in popup_close_tabpage()
and return early in update_winhighlight() if there are
no highlight overrides to update (Foxe Chen).

fixes: #19650
closes: #19670
