…et (pythonGH-152499) Add wait_until_mapped() and AbstractTkTest.require_mapped() to test_tkinter.support and use them to guard the assertions that need a widget to be actually mapped (winfo_width(), identify(), coords(), ...). This avoids intermittent failures under window managers that do not map the widget promptly, without skipping the unrelated checks. Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> (cherry picked from commit 0fff6bd)
