Adding a child theme broke my media library, and I don't know why

I added a VERY basic child theme to add some favicons. I followed the instructions on the how to, and I’ve included the header section of my style.css and the entire text of my functions.php file below.

As soon as I activated this child theme, my media library will no longer load in grid view, but will load in list view.

I searched for help on this and everyone is saying to disable themes and plugins to find the problem. In this case I know my child theme is the problem, but how do I fix it? What did I do wrong?

header of style.css:
