`playwright` causes issues with our `ipcMain` validation

[bpasero]

While implementing the ipcMain validation, we ran into two issues:

• [x] https://github.com/electron/electron/issues/33722 (mitigated)
• [ ] sender.url being an empty string when using playwright for testing

This is impossible for me to reproduce in an isolated sample. Check out https://github.com/bpasero/playwright-electron, it copies a lot of stuff we do in VSCode:

• preload script
• vscode-file protocol
• early ipcRenderer.invoke

To run it just node index.js and see how the URL is printed in the page.

@deepak1556 need your advice how to proceed, how can we instrument Electron app to figure out where the call is coming from?

//cc @pavelfeldman maybe you know if Playwright tampers with Electron startup somehow that could explain this. To clarify: we see a event.senderFrame.url that is the empty string in a ipcMain.handle invocation here.

I was able to reproduce the issue on Windows at least and filed https://github.com/electron/electron/issues/33800 for Electron team to look at, but it might be a playwright issue too.

Nevermind, I had a bug in my sample and I was not able to reproduce and I am running out of ideas. I think to proceed we would have to instrument Electron in a way to figure out why the URL is empty. Sam might a suggestion but I do not see any loading failures.

I will start a project on my own fork, Nice work
