Rendering WebP Images inside a UXP Panel


I am able to reference and display images using an <img> tag inside my UXP panel. I can render jpg and png fine using this method. WebP images do not work ( I would have thought image assets woud be first class citizens in Adobes space). I can find no documentation on supported image types. Can someone please verify if rendering WebP in a panel is supported, if not is there a work around. I have many 100’s of thousand webp assets and I dont wish to convert them.
