The API playgrounds rendered with the RedoclyAPIBlock should show a loading spinner #1638
Description
🙋 Feature Request
API playgrounds rendered with the RedoclyAPIBlock usually load on pages with layout: none, which means that for a short amount of time the page is empty, showing only the top navigation and the footer. When the request to retrieve an OpenAPI definition takes too long it might give the users the impression that the API playground doesn't work at all.
🤔 Expected Behavior
The Redocly API docs library displays a loading spinner by default, but this has been disabled by hardcoding hideLoading: true in the RedoclyAPIBlock. This should be reverted, i.e. have hideLoading set to false by default and allow overriding it on a case by case basis.
😯 Current Behavior
Until the RedoclyAPIBlock renders users see an empty white page.
🔦 Context
See how https://developer.adobe.com/experience-cloud/experience-manager-apis/api/stable/sites/ renders, it's currently a bad first experience until the playground loads.
