Summary:
Staging tests were failing because a popup tip was shown when
anonymous; these tips aren't dismissed by testing hooks during
deployment tests, and so they need to be explicitly dismissed by
tests (in this case, Forks.ts).
grist-core tests were failing because a test suite was accidentally
included that shouldn't have been (BehavioralPrompts.ts).
Test Plan: N/A
