Playground UI doesn't work after upgrade

[avin3sh]

The dev server on release 0.9.11 does not work on the Firefox, more specifically http://localhost:4000/#/dashboard throws lots of resource MIME type mismatch errors in the browser console.

However http://localhost:4000/#/schema page works just fine.

@avin3sh Hey Avinesh! Thanks for posting this one! Could you please try to reset cache and refresh page?

Hi Pavel, Clearing the cache from the earlier version did resolve the issue. My bad I did not try it before.

@avin3sh Hey Avinesh! Thanks for clarifying! I can confirm we have an issue with incorrect caching of index.html for playground so I guess we should leave this open.
