Add common test helper for early ref removal

[jcfranco]

Priority impact

p - low

Summary

We need a test helper to add coverage for use cases where an element might be removed from the DOM to ensure the ref is available when ref-related logic runs.

Desired Outcome

A common test helper that creates and configures a component, then removes it to ensure code that runs after any refs are cleared doesn't throw.

Things to consider:

• certain ref callbacks are invoked in certain configurations, so the helper might need to handle different scenarios
• the test util will likely need to handle the component in the browser context as async Puppeteer API calls might give extra time that hides potential errors
