Just upgrades some of my sites to use 0.97.3 and found that some of SVG icons are not displaying correctly. On the other website background image not working.
As investigated, this was mostly due to the case when SVG is put using pseudo-element ::before
displaying only question mark like an image not found.
Example
.goal1:before {
display: block;

I do a bit of investigation and on 0.97.2 it was even worse, as the below not worked as well.
.webp #front-page {
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url("/images/2016/09/Mitsubishi_twin-scroll_turbo-orange-min.webp");
background-size: cover;
background-attachment: scroll;
background-repeat: no-repeat;
background-position: center top;
overflow: hidden;
}
Similar with 0.97.0
Downgraded to 0.96.0 and all working well. Any ideas?
