+# Port: test(ChatPrompt): avoid using fake timers before suspended (#6688)
+
+**Upstream:** `d0581cf88fa13008871484e5f88fdb0f9f744ff7` (nuxt/ui)
+**Decision:** port
+
+## Upstream change
+Test-only: in `ChatPrompt.spec.ts`'s `re-enables submit after compositionend
+cooldown` case, move `vi.useFakeTimers()` from **before** `mountSuspended()` to
+**after** it, so the fake timers don't interfere with the async suspension
+lifecycle.
+
+## b24ui port — direct 1:1
+b24ui's `test/components/ChatPrompt.spec.ts` matched upstream exactly. Moved the
+`vi.useFakeTimers()` call to right after the `mountSuspended(ChatPrompt, …)`
+block (dropping the now-empty blank line before the mount). Test-only, no `src`
+change.
+
+## Tests
+`ChatPrompt` suite green (62). Full suite unchanged (5289 passed / 6 skipped).
+No snapshot churn.
+
+## Verify (CI=true)
+`dev:prepare` · `lint` · `test` — green. (`typecheck`/`build` unaffected — no
+`src` change.)
