[pgAdmin4][patch] - Fix CheckForViewDataTest

The feature test at pgadmin4/web/pgadmin/feature_tests/view_data_dml_queries.py systematically fails in both our CI pipelines and when run locally. It seems to be because the selenium driver is unable to parse cells of the query result table when is it out of view. This issue seemed to have occurred after our most recent changes to how the feature tests run got committed into master.
