[Webkit-unassigned] [Bug 205717] User Script Sandboxing

--- Comment #3 from Garvan Keeley <garvankeeley at gmail.com> ---
> Brave iOS uses a UUID-namespaced JS object for their WKUserScript injected JS, putting all injected JS in a runtime generated non-introspectable parent object. This seems secure for native-to-JS, I haven't investigated if this is hackable for JS-to-native.

Actually, Object.getOwnPropertyNames would show those functions, so my comment is incorrect, maybe someone from Brave can chime in on their method to secure their WKUserScript JS.
