Description Sam Sneddon [:gsnedders] 2021-10-01 07:13:15 PDT 
Per https://drafts.csswg.org/css-images-4/#invalid-image:

> In some cases an image is invalid, such as a <url> pointing to a resource that is not a valid image format or that has failed to load. An invalid image is rendered as a solid-color transparent image with no natural dimensions. However, invalid images can trigger error-handling clauses in some contexts. For example, an invalid image in list-style-image it is treated as none, allowing the list-style-type to render in its place. [CSS2]

This is the reason why bug 206909 occurred (we end up rendering the broken image icon over the star), rather than the -webkit-image-set() parsing change itself (which is what that bug reverted).
