Intercept and track `MessagePort` traffic

[BurningEnlightenment]

The current electron documentation suggests implementing communication between the main world and context isolated renderer worlds via MessageChannels / MessagePorts¹.

However, this extension isn't really helpful if we apply the above advice as all relevant IPC traffic does not flow through the ipcMain / ipcRenderer interfaces.

Therefore I suggest additionally tracking all MessagePort instances which have been transferred through the relevant ipc interfaces. This would require either intercepting the postMessage calls or the message events.

Thanks for pointing this out. It might take me a while to get back to this since I have my exams rn. I’ll get back to it ASAP and see what I can do.

no worries, good luck and thank you for bringing this extension back to life 🙏
