Firefox content script does not allow clearTimeout and clearInterval to be called in a non-global context #37333
Description
🐞 bug report
Affected Package
The issue is caused by package @angular/zone.js
Is this a regression?
No
Description
A clear and concise description of the problem...When calling clearInterval or clearTimeout in the restricted context of a content script on Firefox with ZoneJS initialized, the call will error out because the function is no longer being called in the context of the window.
🔬 Minimal Reproduction
Difficult to recreate, I'll update my previous testing repo later today.
🔥 Exception or Error
ERROR TypeError: "'clearInterval' called on an object that does not implement interface Window."

Anything else relevant?
This applies only to Firefox Web Extension content scripts, a temporary patch to work around this issue is below, placed after the zone.js import in polyfills.ts:
const patchedClearTimeout = window.clearTimeout;
window.clearTimeout = function(...args) {
return patchedClearTimeout.apply(window, args);
};
const patchedClearInterval = window.clearInterval;
window.clearInterval = function(...args) {
return patchedClearInterval.apply(window, args);
};
