Ordinarily I would ask if this test should continue to run on XQuartz if the problem is only on Aqua:

Suggested change
if sys.platform != 'darwin': # .update_idletasks() does not work.
if text._windowingsystem != 'aqua': # .update_idletasks() does not work.

But this test was already failing on Aqua and XQuartz due to incorrectly negative delta. So this failure may have nothing to do with .update_idletasks(), and the test should not be skipped on Aqua or XQuartz. See #103820, #103821

self.assertIsNone(text.dlineinfo(text.index(f'{last_lineno}.0')))

# Scroll back down using the <Button-5> event.
sidebar.canvas.event_generate('<Button-5>', x=0, y=0)
