summary:

bpo-33951: IDLE test_configdialog: call page.update in setUpClass (GH-7892)


This avoids a failure in at least one case when running only a single
test method rather than all tests in the module.

The issue came up when testing the following on Windows 10 Pro 64-bit:
HighPageTest.test_highlight_target_text_mouse
(cherry picked from commit 2af9f5d334eeca588eeee87d177faf0012c63a03)
