Issue reproduced on Edge 44 on Windows 10 (both on regular PC and using official VM)

Steps to Reproduce

  1. Import MaterialIcons from @expo/vector-icons and try to render one
  2. Open the page in Microsoft Edge

Expected Behavior

Icon is visible

Actual Behavior

TTF file is loaded but the icon is not showing up.

Additionally, but this is not happening in the reproducible demo, in our case we've got a bunch of "3000ms timeout exceeded" errors in the console.

@cruzach this is an issue with expo-font, not with @expo/vector-icons. The fact icon is not visible is due to Font.loadAsync(font) failing even though the font is actually being fetched and loaded properly

Thanks! Seeing now that expo-font has fontfaceobserver as a dependency
