Use case or problem
When you paste a rich text (with embeded images) it keeps the images in a data url format
!(data:image/png;base64,<HUGE chunk of characters) making the edit for of the note un-manageable
The image should be auto-downloaded and saved in the vault as the paste from clipboard works for a single image.
Current workaround (optional)
You have to give something as 6 # before and after the data url in order to fold it, and hide it.
