// The address and token screens do not report a transaction list 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 fetch() fails with the same "Failed to fetch" as a
// server that cannot be reached, so the explorer request here always fails
// 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.
