Subject: [PATCH] test(mobile): pin the working row's live region across both
 states
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deleting the prop, or the plausible-looking `stale ? 'polite' : 'none'`,
both left every case green. The contract is that the mode is constant —
Android drops the announcement if it is switched on in the same commit
as the content change — so it has to be asserted in both renders.
