The browser Safari indicated that there is a missing image

[Pageboy]

Describe the bug
In the editor at the point of editing a post or page, there is a missing image displayed top left.
This only seems to happen in Safari on MAC

To Reproduce

Use Safari Version 14.1 (16611.1.21.161.6) on MAC 11.3.1

It looks like Safari does not support inline svg in content: url();

So I put
*:before, *:after { display: none; }
in my responsive css and that seems to fix it. Did it break anything else?

I figured out that the SVG code need to be encoded before using it in pseudo CSS. Use URL-encoder to encode the svg, I had a try and it is displayed correctly. Can this fix be applied?

Maybe this issue has been fixed ? @erezrokah
