X-callback-url Support and Reference

I’ve just created a Shortcut that seems to almost successfully create a note with an image attachment using the URL scheme and base64 encoding. The image appears as a thumbnail in the note as I would expect; however, when I long press the image to get the image options popover, the “Preview” button does nothing. When I insert an image into a note normally, this button shows a full-screen version of the image. Does adding images via the URL scheme make the Preview function not work?
