1972974 - assertBothRejectDOM expects Promise.all to handle callback from dying windows.

Status: ASSIGNED

(Core :: DOM: Navigation, defect)

Description

[Andreas Farre [:farre]]

assertBothRejectDOM is used in places where we expect a callback attached to promise from a removed iframe to be handled, e.g. navigation-api/navigation-methods/return-value/reload-already-detached.html. This doesn't work because of how Promise.all is specified, see this discussion.

assertBothRejectDOM can be re-written to not use Promise.all, which is the proposed solution.

Introduces waitForAllLenient, which behaves similarly to Promise.all,
but allows for promises from a detached iframe's realm to participate.
