Modernizr: videoautoplay not working on Safari 11

[JonathanDoelan]

Because Safari 11 disables "unmuted Videos" modernizr gives me a wrong result.
The modernizr-test here should include the video-attribute "muted", so that the test returns a positive result!

With or without this attribute, the test return false for me - Safari 11 - Macos Sierra.
This test work well https://codepen.io/paulorely/pen/QveEGy

It's always returning as false for me on Safari 11 also.

Running macOS Sierra 10.12.6 (16G29)
Safari 11.0 (12604.1.38.1.7)

Apparently, Safari 11 starts autoplayback only if video element is visible on the client area. So, if the video element style contains 'display: none' or 'height == 0' or 'width == 0' safari does not start it
