The resizeMode prop on the Image component does not work correctly - cover seems to behave the same as contains. This can easily be seen in the RNTester image example. There is also weirdness with window resizing where the image will render multiple times with different layouts.

Steps To Reproduce

1. Build and run RNTester-macOS
2. Open example
3. Scroll to 'Resize Mode' section

Describe what you expected to happen:

The "Cover" example should be completely covered by the image, but it is letter-boxed the same as the "Contain" example next to it:
