Electron 7.0.0-beta.6 Broken Shared Worker

Used devmonkey22/electron-renderer-leak as a base.

The main process registers a protocol app:// so that the SharedWorker will actually be shared.

SharedWorker does not execute

Two windows should open and each post a message to the SharedWorker. One window should say "Result: 0" and the other should say "Result: 1"

Click the button in each window to post a message.

If it's working (as it is in Electron 6), a message should appear that says "Result: N", where N is the number of times a message has been posted.

If it's not working, the message will say "No clicks yet."

There is a second button that says "Create Worker with Data URL", which creates a SharedWorker with a data URL.

Clicking this button in Electron 6 creates a functional worker.
Clicking this button in Electron 7 crashes the renderer.

If you edit main.js to disable nodeIntegrationInWorker, the SharedWorker object is created, but the worker is still non-functional.
