It should not receive this even here at all, this doesn't fix the issue, it hides it

Thanks for the review @sheremet-va - agreed this is a symptom and not the root cause.

I still don't know exactly how iframes of two or more tests end up communicating, potentially an iframeId collison.
I've simulated the behavior with a second broadcast channel that echos with the response: prefix unguarded. Additionally added the guard around postMessage. With the browser package from main, the test exhibits the infinite loop that crashed my computer a few times. With the guards, it passes without error.
Avoid infinite response event loop by only sending response messages for events that were successfully handled. Changes: - Add eventHandled flag to track successful event processing - Only call channel.postMessage for handled events - Add reproduction test 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
