Investigated in T273327#6884379.
There doesn't appear to be anything wrong with the test.
@Addshore would proposed doubling the timeout for this test... (and similar waits / timeouts)
**Acceptance Criteria:**
[] Set the timeout for this wait to be higher (inline with what the timings in the investigation suggest might be okay)
[] Increase timeouts in other places where waitForDisplayed, which is related to an API call, is being used.
