Description: In test_sidebar.test_mousewheel, only use the X11 / events when testing on x11 Tk before 8.7. Otherwise, use as on other systems. In test_configdialog, assert the 'disabled' state flag alone instead of the exact ttk state tuple (which transient pointer states break), and restore the tests' method masks with addCleanup(). (cherry picked from commit a2581eb) Co-authored-by: Serhiy Storchaka storchaka@gmail.com Co-authored-by: Claude Opus 4.8 (1M context) noreply@anthropic.com Issue: gh-153741
