Electron Releases

Description of Change

• Returning { redirectURL } from a session.webRequest.onBeforeRequest listener for a CORS preflight request crashed the main process; the preflight now fails instead (redirecting a preflight is not supported), matching the upstream extensions implementation this code is derived from.
• With an extension that has the webRequest permission loaded and no session.webRequest listeners registered, net.fetch() / net.request() from the main process crashed because the frameless URL loader factory was handed to the extensions WebRequest layer as a navigation factory. Main-process factories now stay on Electron's own proxy.
• Adds a crash-case fixture for each.

Checklist

• PR description included
• npm test passes
• tests are changed or added

Release Notes

Notes: Fixed crashes in the main process when a webRequest.onBeforeRequest listener redirected a CORS preflight request, and when calling net.fetch() with a webRequest-permission extension loaded.
