I have tried two fixes, but neither of them are suitable: - https://github.com/grafana/xk6-browser/pull/512: This adds a locking mechanism to ensure that the `clearContext` event is worked on before the `createContext`....

Ok, WDYT?: To ensure that the event publishing [goroutines](https://github.com/grafana/xk6-browser/blob/ae264530b6fbe0285ac9df9b0f4a907b460bb805/common/event_emitter.go#L183) don't break the ordering of the emitted events, we could get the [emitEvent](https://github.com/grafana/xk6-browser/blob/ae264530b6fbe0285ac9df9b0f4a907b460bb805/common/event_emitter.go#L168) goroutines to synchronise. What I mean by this...

We think the deadlock issue in the cloud ([#496](https://github.com/grafana/xk6-browser/issues/496)) is the same as issue as the test timeout issue in waitForExecutionContext ([#482](https://github.com/grafana/xk6-browser/issues/482)).

This works with the default `BrowserContext`, but it doesn't work when a second context is created.
