"Add media" button doesn't always open the media library

Overview

As I've been creating content with XB, I'm noticing that quite often the "Add media" button doesn't actually work after I have been interacting with XB (i.e. build content). After I refresh XB, the "Add media" button works again.

Steps to reproduce:

1. Load XB with two components using image placed in the canvas
2. Open component 1 and click "Add media"
3. Close media library
4. Open component 2 and click "Add media"
5. Close media library
6. Go back to component 1 and click "Add media"
7. Notice, media library does not open

Proposed resolution
