1576288 - Fix dom/tests/mochitest/storageevent/ tests to work with Fission

Status: RESOLVED FIXED

(Core :: Storage: localStorage & sessionStorage, task, P2)

Description

[Andrew McCreight [:mccr8]]

These tests compute the origin of their parent, in order to pass in as the target origin argument to postMessage. They do this with SpecialPowers.wrap(parent.window.location); which does not work with Fission enabled, because the parent is often in another process. Every web page in this directory is only ever has a single origin as a parent, so we can hard code it as an argument to the first call to the postMsg() helper method.
