Log excerpt

FAIL src/pages/TemplateVersionEditorPage/TemplateVersionEditorPage.test.tsx > Use custom name, message and set it as active when publishing
Error: Test timed out in 5000ms.

An update to PublishTemplateVersionDialog inside a test was not wrapped in act(...).
An update to Tooltip inside a test was not wrapped in act(...).
An update to ForwardRef(FormControl) inside a test was not wrapped in act(...).

Root cause assessment

• Flaky UI test timing out waiting for async publish dialog interactions. The repeated act() warnings indicate state updates not awaited, which can cause sporadic timeouts.
