Increase timeout for flaky test

[yschimke]

Increasing the timeout which only has 250ms tolerance after inbuilt delays etc. Issue info is here #5304

[yschimke]

To be clear it shouldn't be flaky after this PR, but this will record the events for every test run, so we can observe typical response times.
