@dan What is the timeline for adding full support for WebP in Elements?
Currently, WebP works great in preview, but not in the editor. If you are using a WebP image with a transparent background, the editor will always render it with a WHITE background. This makes it very difficult to create WYSIWYG designs with a WebP image with a transparent background.
I discovered this problem while writing a custom component where I literally spent hours trying to figure out why my transparent WebP image was not rendering transparent in the editor.
These days I pretty much only use WebP images, so I hope we see full support in the near future.
