10 years ago This is intended because we use images to preload resources certain versions of webkit in yepnope. There's nothing we can do about the warnings.

If modenizr does preload as they said, it shouldn't affect our loading speed.
Seems like it's interpreting the response as an image and therefore downloading it twice.. in some browsers this appears to cause a delay in the app loading.
