Seems that there is no way to set nonce attribute for a Web Worker in order to allow sandbox to do whatever it wants. Maybe there must be a way to set nonce-attribute in header or/and in script string/attribute?

I'm trying to run every unsafe-code in web worker's sandbox but only Chrome understands separate policy for the worker. And because of that I need to run 'unsafe-eval' policy just because I'm using template engine, and that can cause issues and not really offering me a protection.
