Currently when hot reloading, applications can correctly load new assets in the application. Fonts are also copied to the devfs by the same logic, but adding a font does not allow it to be used until the entire application is restarted.

When running an application and adding a font, neither hot reloading nor hot restarting allows it to be used.

When running application and removing it a font, it can still be used after hot reload or hot restart.

My guess is that the fonts are being read only from the original application bundle and not the updated devfs directory.
