[Feature request]: implement equivalent to Playwright’s .toPass or .poll

[ihsib]

Is your feature request related to a problem? Please describe.

We are currently facing issues with Storybook runner visual tests failing due to incomplete hydration. We’ve experimented with both the mask feature , waitForPageReady and the waitFor method using Promise.all and custom polling, but the results remain inconsistent. Additionally, we’ve noticed that sometimes the masked elements seem to shift, causing tests to fail.

Describe the solution you'd like

Given that the Playwright package is already used in the Storybook runner, we suggest integrating the .toPass or .toPoll method. This could help improve the reliability of our visual tests by providing more consistent and readable assertions.
