test: fix flaky ppom test

[pnarayanaswamy]

Description

Sometimes it takes a little longer for the spinner to go away and for the blockaid banner to show up. Just increasing the dynamic timeout waiting for the spinner to be removed from the page so that in the situations where it takes a little longer the tests don't fail.
