[bug] SVG sprite doesn't work after update to iOS 9.3

1

Hi,

I store all my SVG icons in one sprite and use it like that:

    <ion-nav-title>
        <svg class="dropShadow">
            <use x="0" y="0" xlink:href="img/sprite.svg#logo1"></use>
        </svg>
    </ion-nav-title>

It worked perfectly on iOS 9.2, but on iOS 9.3 all icons are missing.
Is that a bug? Any ideas?

Thanks.
