The Settings round trip switched the theme and the network and closed
the popup at once. A close before the change handler's save lands loses
the switch, and the suite then ran on Sepolia.
tests/e2e/run.js now has one helper that polls a field of the stored
record until it holds the expected value, in place of the wait that
only read viewStack. Each Settings switch and spam-filter toggle waits
for its save, the recovery-phrase reopen waits for its saved view, and
reopenPopup() waits until the view it expects to reopen on is the saved
one. README.md no longer lists #446 among the open reports of the
Chrome suite failing under load.
