There are a couple of temporary workarounds here:
angular/angular.js#17117 (comment)

In https://bugzilla.mozilla.org/show_bug.cgi?id=1700931, Firefox said that clearing the window.name on cross-origin navigation will continue and the flag to disable it will be removed at some point.

The following long-known AngularJS/Protractor issues are related to window.name being cleared on iOS and macOS:

• Safari security fix broke window.name usage here: #4004
• Appium doesn't support this window.name setting either: #2840

Additionally, Chromium is getting closer to shipping the clearing of window.name in a beta:

As this feature is a synchronization of both AngularJS and Protractor, a solution would likely need to involve both. That's why this issue exists in addition to angular/angular.js#17117, which requests a fix for this during the AngularJS LTS period (prior to the end of December 2021).
