Subject: [PATCH] Fix the `gets text content, with correct properties (issue
 8276)` unit test

This unit test failed consistently in Firefox both locally and on GitHub
Actions (but not in Chrome or on the bots), which suggests a timing issue.

Since all other unit tests that rely on `commonObjs` actually render the
page, most likely to make sure that `commonObjs` is fully populated at
the time of the check, this commit mirrors that approach to this test,
which indeed fixes the issue.
