Fires before custom font is applied

I'm having to use jquery.fontspy.js to hold off balancing until my @font-face applies. Otherwise it balances according to default font.

Reproduce the reported case with a custom @font-face and compare balancing before and after the font applies. Use jquery.fontspy.js as the reported workaround and determine the expected point at which balancing should occur; done means text is balanced using the custom font without requiring that workaround.
