Can't create token with transparent background

I'm trying to use this image as a token:&nbsp; <a href="https://toppng.com/uploads/preview/emoji-monkey-face-11549728638tfaeuueunn.png" rel="nofollow">https://toppng.com/uploads/preview/emoji-monkey-face-11549728638tfaeuueunn.png</a> It's got that transparent background (the gray/white checkerboard) at every step of the way - on the web, in my file system, and in the character journal, but when I drag it onto the board, it's got a white background.

I've notice Google Image Search doing this lately. It looks like it has a transparent background, but that checkerboard pattern is actually baked into the image.
