Issue Description

Hello everyone. Just tried latest dashboard version 3.3.0 and in Dashboard GUI file uploading don't work. Just nothing happens when trying to add or replace file in a File field of object. No errors in dev tools console and no requests in dev tools network tab. I was using ver 2.1.0 before. It works there. tried 3.2.0 and 3.2.1 - everything works well. So I guess this problem started from 3.3.0 and newer.
Searched for the similar issues hoping find solution but didn't find anything.
