Attachment has no icon in received mail, making it near impossible to find

On MacOs Ventura 13.1, when I receive a mail with an attachment, I need to select text to find the attachment as it has no icon (it basically is a white square on white background with no contours).

It's incredibly annoying as the attachment is there, can be opened, previewed and everything. It's just a matter of finding where it is in the body of the mail.

See screenshot attached, the light grey square is not visible because I found it and selected it. Otherwise you'd just see white there...
