+ Web fonts retain their downloaded data in case they need to send that data to the GPU process
+ to render into canvas. Small caps fonts are implemented by creating a "derivative" variant font.
+ When we were creating these derivative fonts, we weren't forwarding this downloaded data to
+ those new fonts. Without it, the font fails to transfer across IPC.
