AutistMask/tests/transactionListCancelled.test.js

// The address and token screens do not report a transaction list, or an ENS
// name lookup for the addresses in it, that the popup's own closing cancelled,
// and still report one that failed while the popup was open
// (https://git.eeqj.de/sneak/AutistMask/issues/475).
//
// In the popup a cancelled request fails with the same "Failed to fetch" as a
// server that cannot be reached, so the requests here fail that way, and only
// the signal the popup aborts on pagehide tells the two cases apart. Driven
// against a minimal DOM stub in the shape tests/timestampDisplay.test.js uses.

// The explorer answers with mockHistory, and fails when it is null.
