Fix CI test failure which started happening in this test after the
addition of Window::ContextHelpCaptureLost in e04e3260fc (Handle
context-help mouse capture loss, 2026-07-08) because the child window
that was not supposed to be repainted still was, as the entire window
needed a refresh.
Refresh and update it before starting the test to make it pass again
reliably.
See #26726.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
