rfc: Preload Realm for Service Workers

[samuelmaddock]

Preload realms provide an isolated context to run JavaScript prior to code evaluating in another
context. This expands functionality of Electron's preload scripts to provide new context targets.
This proposal intends to target Service Worker contexts with potential plans for new contexts (web
workers, shared workers) in future proposals.

If you're curious, there's a very rough wip prototype being written in https://github.com/samuelmaddock/electron/tree/feat/preload-realm

Hello, is there any updates? I think Service Worker contexts support loading preload script is a cool propose.This will be able to extend the extension API that electron does not support

Also wondering about an update on this. We need modern chrome extensions support in electron, and we currently rely on the electron-chrome-extensions package.

Any updates on this? This is a showstopper for our project right now, would love to see this implemented.

GitHub is stuck on "Processing updates", attempting to close and reopen to fix this.
