problem accessing playground related url's from within playground #2373

Block-Based Visual Blueprint Builder Plugin Works fine in standalone mode, but a few things break in the playground. As per my understanding, the service worker intercepts all the requests to https://playground.wordpress.net, which affects the following:

1. fetch request to schema.json 404 as the service worker is trying to load this from the worker cache
2. Link to open a fresh playground with blueprint JSON fails as it routes the request to the current playground scope
3. Link to open blueprint in BluePrint Builder (code editor) as it routes the request to the current playground scope and 404

Steps to Reproduce
