            Bug ID: 186930
           Summary: Element.animate() called with a positive delay does
                    not animate
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Macintosh
                OS: macOS 10.13
            Status: NEW
          Severity: Normal

Animations specified with a positive delay in its Timing options do not visually start animating. It seems undefined, zero, and negative delays are all working as intended.

Example:

In the example, the second row circles are the only ones with positive delays specified and should be animating as well.

Steps to Reproduce:
1. Setup an animation such as:

element.animate([ { transform: 'scale(1)' }, { transform: 'scale(.5)' } ], {
  duration: 1000,
  delay: 500
});


Expected Results:
After 500ms, the element will start to scale to .5 over the course of 1000ms

Actual Results:
No animation occurs, and the element stays at scale(1).

Build: Release 59 (Safari 12.0, WebKit 13606.1.21)
