Two Chrome end-to-end cases send ETH and leave the wait for its receipt
running. In one, lookups answer "no receipt" until the 60-second deadline
ends the wait with the timeout message. In the other, a new fixture switch
makes every receipt lookup fail, and the sixth failure in a row ends the
wait with the message naming the unreachable network. Both check the exact
message and that Done returns to the address screen. Both wait in real
time: Playwright's clock would apply to every later test, and backdating
the stored broadcast time races the popup's own save.
