The root cause is related to the lack of `focus` event, and bug 1395928 discussed this already. Hence, I think this bug can be duplicated to bug 1395928.

Per comment 2, the fix of this bug depends on an undefined behavior, which is currently being discussed in bug 1395928. Since bug 1395928 isn't a blocker and paypal.com isn't the targeting website, I'd like to remove it from the V2 scope.
