1. Add two or more iframes on the page with custom font (@font-face).
2. Refresh page.

What is the expected behavior?
Texts are visible with correct font.

What went wrong?
The texts using custom fonts are not visible sometimes, however fonts are loaded and text exists. 
If you reload iframe, text will be shown.
If you inspect element that contains invisible text and change it's any CSS property or turn on/off text will appear.
