testTableReportFunctionalTest is failing on the CI

The test testTableReportFunctionalTest fails on the CI but not when run locally.
It looks like an issue with the selenium webdriver...

For now, it goes away when I add some delay to the test execution, though I don't see why that is needed.
I added it to https://github.com/SeasideSt/Seaside/tree/refs/heads/pharo13-development
