Subject: [PATCH] feat(editor): Gracefully ignore invalid payloads in
 postMessage handler (#8096)

It's possible for browser extensions to send `message` events to an n8n window.
This change improves the already existing check to ignore invalid messages.

Fixes https://community.n8n.io/t/errors-in-the-browser-console-on-n8n-1-version/33910
