Let's call this one {{done}}. Disabling those 2 flaky ContentEditable tests (T401573: Flaky VisualEditor Selenium test: Content Editable should insert a table) brought us down to only 2 build failures in the past month. The global flaky test failure rate also fell to an average of 2.5% from a prior benchmark of an average of 9.4% as measured by the flaky-tests dashboard.
