The clicking unread thread message notification opens thread message feed e2e is failing. It does seem to pass on the 3rd run in a lot of cases.

In https://gitlab.com/gitlab-org/gitter/webapp/merge_requests/1642, I already tried to make the test more stable by waiting for the textarea to be all done expanding its own height (see pictures 1 -> 2, or 1 -> 3).
I also created an issue in the Cypress tracker to more broadly track layout shifts causing clicks to miss the target, https://github.com/cypress-io/cypress/issues/5662
You can see the extra layout shifts as it goes through the test which probably make the click miss the element: between pictures 4 -> 5
