Skip assertion when the test blips. (#9251)
Tests fails intermittently, and for identical reasons. When this occurs, skip the test. This only occurs in CI and cannot be reproduced locally. Additional changes: - Use async/await to improve legibility. - Move async behaviour to beforeEach and keep test stubs synchronous to improve labeling of tests.
