// Lifecycle tests for the post-broadcast transaction status views
// (src/popup/views/txStatus.js).
//
// The bug these pin down: the receipt poll rendered both outcomes on the tick
// that crossed the 60-second deadline, so a confirmed transaction was replaced
// by "not confirmed within 60 seconds" — the user is told their transaction
// failed when it succeeded. The same shape applies to any callback that
// outlives its wait: a receipt lookup still in flight when the view is left
// must not render over whatever replaced it.
//
// Fake timers make the race deterministic: the receipt promise is already
// resolved when the deadline tick runs, so in the unfixed code showSuccess()
// is always followed by showError() on that tick.
//
// No network: getProvider is mocked at the module boundary and there is no
// jsdom in this repo, so the handful of DOM calls these views make are served
// by the stub below.
