This is a video tag with an MP4 source that fails and falls back to another MP4 source: http://jsfiddle.net/p4u5oLva/9/
When loaded in Safari, it requests the fallback video immediately after the first source fails.

This is a video tag with an HLS source that fails and falls back to another MP4 source: http://jsfiddle.net/p4u5oLva/8/
When loaded in Safari, it requests the fallback video 20 seconds after the first source fails.

Tested with Safari 11.1 (13605.1.33.1.2).

WebKit QA confirmed this is resolved, most likely in AVFoundation.
