Two flaky tests that need investigated

[MiYanni]

Summary

While being domestic cat, I noticed a couple of tests that are inconsistent/flaky. These tests will cause build failures, but a rerun of the PR CI pipeline will often result in success. These test failures can be seen when searching the Helix test log for [FAIL]. The Helix test log link can be accessed when checking the build failure by following the Failure log: link:
