NoScript preventing some images from loading

[rickmastfan67]

Windows 7 x64 SP1
Firefox 34 Beta 5
NoScript 2.6.9.3

Steps to reproduce:
1. Start with a fresh profile.
2. Load the following site: http://www.masgrafx.com/
3. Hover the mouse over the 'About Us' text.
4. Notice that there are images infront of the text in the hovering window 'About Us' & 'Meet The Team'.
5. Now, install NoScript.
6. Reload the side and redo Step #2.
7. Now, allow all 3 sites that have scripts to run.
8. Now, redo Step #3.

What happens:
You can see that the icons you saw in Step #4 don't show up.

What should happen:
The images from Step #4 should show up.

Does anybody know what's causing this? Is it because the 'images' are a font?
