Lee en Lib/test/test_tkinter/test_misc.py alrededor de WmTest.test_wm_iconbitmap y la ubicación del traceback en Lib/tkinter/init.py:2345. Reproduce el timeout en macOS / build and test (macos-26-intel) con Tk 9.0.3 y, después, revisa los PR enlazados; se considera terminado cuando la prueba finaliza dentro del tiempo de espera de CI.
