Autoplay muted in Safari + iOS 12 resolving to false while it should work

[gcarrion-gfrmedia]

While using the can-autoplay demo page it shows that autoplay muted does not work on iOS 12 + Safari. However, when using a player like JWP it does autoplay muted on the same device/browser.

See this video where can-autoplay resolves autoplay muted to false, but it works with another video player.
