Request: Support for Testing Library Playground Utility

[Noriller]

Issue description or question

Testing Library has this convenience:
https://testing-library.com/docs/dom-testing-library/api-debugging/#screenlogtestingplaygroundurl

This opens the playground with the exact dom that's being tested. If, as you're changing code it would open that somewhere and keep updating... it would greatly speed up testing the frontend.

Today I'm logging the URL, and clicking the link every time I need to see changes.

It could be, perhaps, a tab running like an iframe inside the tests explorer that opens in the browser. Each change changes the value that reloads the page.

Thanks for the feature suggestion. This is something we had briefly considered in the past, but we're not entirely sure how expensive this would be or how much overhead it would add.

Marking as a feature request, and we will evaluate in our future planning.
