The flakiness seems to be some Features initialization flakiness problem
and not related to the logic under test. Not going to pursue further here.

Deflake resource loading hints and previews browsertest

Attempt to deflake resource loading hints and previews
browsertest by waiting for hints to be processed.

Currently, the hints are processed on the background thread,
and so may not be processed immediately.

Log from the failed Linux test bots seem to indicate that
the hints are not processed in time.
