Angular 7 animations causes z-index overlapping issue on webkit browsers

I have added some staggered animations to my angular 7 app for elements to animate on page load. I have encountered this weird z-index issue on one of my components.

The animation code is this:

@Component({
  selector: 'track-page',
  templateUrl: './track-page.component.html',
  styleUrls: ['./track-page.component.scss'],
  animations: [
    trigger('fadeIn', [
      transition(':enter', [
        query('*', style({opacity: 0})),
        query('*', [
            animate('500ms', style({opacity: 1}))
        ]),
      ])
    ]),
    trigger('swipeUp', [
      transition('void => *', [
        query('*', style({opacity: 0, transform: 'translate3d(0,20%,0)'})),
        query('*', stagger(10, [
          animate('700ms ease-in', keyframes([
            style({opacity: 1, transform: 'none', offset: 1})
          ]))
        ]))
      ])
    ])
  ]
})

This code causes the following result only on webkit browsers:

The share component should appear in front of every other element however the metronome icon appears ontop. I have tried setting the max z-index on the share component but have had no luck.

I had similar problem with z-indexes and animations (items with indexes > 0 was overlapping component during the transition), and this article was very helpful. You just have to set z-index in style for before and after the animation. Don't forget position: relative to make the z-indexes work.

transition(
    "void => prev", // ---> Entering --->
    [
        // In order to maintain a zIndex of 2 throughout the ENTIRE
        // animation (but not after the animation), we have to define it
        // in both the initial and target styles. Unfortunately, this
        // means that we ALSO have to define target values for the rest
        // of the styles, which we wouldn't normally have to.
        style({
            left: -100,
            opacity: 0.0,
            zIndex: 2
        }),
        animate(
            "200ms ease-in-out",
            style({
                left: 0,
                opacity: 1.0,
                zIndex: 2
            })
        )
    ]
),

I have found a solution, I tried changing my translate3d to just a translateY but it didn't make a difference. So I set transform: translate3d(0, 0, 1px); on the share component that was meant to have the highest z-index the share component now overlays every other element correctly on all browsers.
