New card visual not displaying Base64 encoded SVGs

[MattB-Motive]

Hi 

I am trying to display Base64 encoded SVG images in the new Card visual. Standard SVGs and Base64 encoded JPG/PNGs work fine. But not Base64 encoded SVGs.

Red Dot Base64	data:image/svg+xml;base64,PHN2ZyB3aWR0aD0iMTAwIiBoZWlnaHQ9IjEwMCIgeG1sbnM9Imh0dHA6Ly93d3cudzMub3JnLzIwMDAvc3ZnIj48cmVjdCB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBmaWxsPSJyZWQiLz48L3N2Zz4=
Red Dot SVG	data&colon;image/svg+xml;utf8,<svg width='100' height='100' xmlns='http://www.w3.org/2000/svg'><rect width='100%' height='100%' fill='red'/></svg>

Any ideas?

Thanks

Matt

@MattB-Motive - did you ever find a solution for this?  I'm encountering the same issue.  I'm on the Sept.2025 release and it still appears to be an issue.  I can't get the base64 svg images to work in any type of visual.  I've confirmed that I'm using the correct prefix (data:image/svg+xml;base64,) and my column is formatted as an Image URL.  I can't seem to find any other threads that confirm that this is an known issue.  I'd appreciate it if you could share anything you've learned.

Thanks,

Joe
