-webkit-animation stops when scrolling on mobile safari

问题

I'm making a css3 loading animation for a mobile website. The loader works just fine by using the following HTML / CSS:

HTML:

<div class="loader"></div>

CSS:

    .loader {
    background-color: rgba(0,0,0,0);
    border: 6px solid rgba(0,0,0,0.75);
    opacity: 0.5;
    border-top: 6px solid rgba(0,0,0,0);
    border-left: 6px solid rgba(0,0,0,0);
    border-radius: 60px;
    box-shadow: 0 0 5px rgba(0,0,0,0.5);
    width: 60px;
    height: 60px;
    margin: 0 auto;
    -moz-animation: spin 1s infinite linear;
    -webkit-animation: spin 1s infinite linear;
}

    @-moz-keyframes spin {
        0% { -moz-transform:rotate(0deg); }
        100% { -moz-transform:rotate(360deg); }
    }

    @-webkit-keyframes spin {
        0% { -webkit-transform:rotate(0deg); }
        100% { -webkit-transform:rotate(360deg); }
    }

However, when viewing the animation on mobil safari, the animation will pause when the page is being scrolled / touched. Is there any way to keep the animation going even if the user is scrolling the page?

Thanks!

I do not believe this is currently possible. You have to do your own scrolling implementation (or use a framework) to avoid this side effect. I speculate, but would welcome a more technical insight - that this is because both native scrolling and CSS Animation contend for GPU control - they both can't have it
