// Step 1:
// - Parent: (current URL)

// - i2: resources/navigation-back.html
// Step 2:
// - Parent: (current URL)
// - i: /common/blank.html?endI

// Then, calling navigation.back() in i2 will take is from step 2 to step 0, which would navigate i.
// That is not allowed, so the call to back() must reject.
