lyndonr on "Media Library View Defaults to "Uploaded to this post" Function"

I found a nice fix to make this happen in the feature request forum

This bit of code for functions.php

It was only a week later I discovered it breaks JS drop down functionality in the Admin. Not sure if something changed when I updated to 3.6.1.

Is anyone else using this function successfully?

Thanks in advance!
