A brief skim through that doc looks like it is about a kind of security that's not relevant to my project. I'm trying to protect the user from themselves while simultaneously giving the user full power over the document. Web workers are interesting and relevant to this use case, however the almost total isolation doesn't lend itself to manipulating the DOM without the user explicitly writing a custom API to interpret the worker's messages. So, back to the same problem. Thanks for the link. I'll do some digging into chrome's sandbox[1]: [1]: https://chromium.googlesource.com/chromium/src/+/master/docs/design/sandbox.md https://chromium.googlesource.com/chromium/src/+/master/docs...
