How do you test WebSocket connections reliably in Playwright?

We have a real-time dashboard that uses WebSockets and I'm struggling to write reliable tests for it.
The main challenges:
- Asserting that a specific message was received after a user action
- Testing reconnection behaviour when the socket drops
- The timing between socket messages and DOM updates is non-deterministic
I've looked at `page.on('websocket', ...)` but the API feels low-level and I'm not sure how to build a clean abstraction on top of it. Anyone done this in production test suites?
