The timeout in an RPQuestionStep seems to time out too early

In the example app, the following timeout for 6 seconds seems to time out already after 1-2 secs:

```
final alcoholStep = RPQuestionStep(
identifier: 'alcoholStep',
title: 'When did you last drink alcohol?',
answerFormat: dateAnswerFormat,
autoSkip: true,
// TODO - something is wrong - this step time out after 1-2 secs
timeout: Duration(seconds: 6),
);
```

Start in the example app with the RPQuestionStep snippet for alcoholStep and reproduce the six-second timeout while observing the actual elapsed time. Trace the timeout behavior for RPQuestionStep and verify the step remains available for the configured duration; add or update a relevant test if the existing test structure identifies one.
