in the WKWebview /safari scaling a scrollable container results in a pixelated output the issue occurs when the container div uses ```overflow: auto;``` or ```overflow:scroll;```

scaling was working fine in macOS Catalina but broke with the OS update

here you can find a example of the issue https://codepen.io/thelastairbender/pen/bGqPEKY

are there any fix or a workaround for this issue, any idea would be great

this is not the duplicate of the bug 27684, in bug 27684 the issue is content is pixelated while scaling but settles own after scaling finish, but in this case content stays pixelated after scaling finishes

That's because the pixelation happens when the element is rendered into a composited layer. In bug 27684 that's temporary while the animation is running. Here, async scrolling logic means that it's permanent.
