This is mainly to enable TamperMonkey to continue using scripts that have `@require` dependencies on sites with a restrictive `Trusted-Types` policy. At least until TM v4.14 comes out, the milestone has already been added: https://github.com/Tampermonkey/tampermonkey/issues/1334#event-5361683856 \n Make sure this script is executed before the `@require`ing of any dependencies

// This script provides pass-through policies to try to enable you to do what ever you want with the DOM, while trying not to disturb any defaults in place.
// Basically, if you have to create your own Trusted Types (e.g. TrustedHTML), and if the site's CSP allows for the creation of new policies, you can use a permissive policy to wrap your strings into a Trusted Type, like TrustedHTML, which the browser will then allow you to assign to the DOM.
// Best case scenario: The site has no default policy set. This allows us to specify our own, in which we can then allow everything (pass-through); this will restore all ability to modify the DOM.
// If we have to create a custom policy, all contents have to be piped through the relevant function of the TT Policy, like `TTP.createHTML("unsafe string contents")`, which will then return trusted contents.
const overwrite_default = false; // If a default policy already exists, it might be best not to overwrite it, but to try and set a custom policy and use it to manually generate trusted types. Try at your own risk
