Triage frontend act warnings

[fzhao99]

Background

As detailed in several previous PR's, our frontend tests sometime get cluttered with act warnings. These are coming from component side effects triggering after a testing block and may contribute to flakiness / indeterminate tests. See the writeup in this PR for more details.

We're getting act warnings in places we shouldn't be though and are currently getting around it by wrapping our tests in act, which isn't recommended. Fixing the issue has been a bit of a headache but might be related to a mismatched subdependency shared by several testing library. Bob has explored this fix initially on a separate branch and found promising results.

Action requested

Triage fixing the frontend act warnings. Push to a separate feature branch any quick straightforward fixes and make tickets for the rest.
