16792	File Browser error handling	yev		"I am using '''File Browser''' and '''File Uploader''' plugins. One of the requirements for me is to prevent requests exceeding some max size from succeeding on the server side. The server echoes back a json: {""uploaded"":0,""error"":{""message"":""Too large: 10,240Kb""}}

File Uploader (copy/paste directly into editor) works. I get a balloon message: 'Network error occurred during file upload.'

But File Browser does not work. It shows no useful message except for broken page inside the uploader iframe. And the worst part is - it completely hoses the Dialog. User can no longer exit it or re-upload new file. It shows this error:
VM2738:formatted:2659 Uncaught DOMException: Blocked a frame with origin ""http://localhost"" from accessing a cross-origin frame.
