Steps to reproduce:

1. Go to Content -> Documents And Media.
2. Add a new file.
3. Click on its name.

Expected: The sharing button at the top is white with grey border (secondary style).
Actual: The sharing button has no border, it is only text.

The same happens with the sharing button inside the info panel.
