Frontend unit tests run in a plain node environment, so nothing that renders can be covered and no hook can be tested under real React. The workaround that forces is already in the tree: the use-global-shortcuts test mocks out react itself, so its useEffect never re-runs on a dependency change and never goes through React's commit/cleanup ordering -- it pins the stub rather than the hook. Split the suite into two rstest projects: *.test.ts(x) keeps running on node, *.dom.test.ts(x) runs on happy-dom. A global DOM environment was measured first and rejected -- it takes the same 743 tests from 3.3s to 9.5s -- and rstest has no per-file environment docblock, so projects is the only way to charge that cost to the tests that need it. useIsMobile is the first consumer: it had no tests and cannot have any without a document, since it reads window.matchMedia.
