Image in extra:: does not work

[1over137]

Describe the bug
Image in extra:: does not work

But in Anki

Steps to Reproduce:
Add a flashcard with image in the extra field

Image does not show up in the flashcard.

It is necessary to have the image in extra field in the case of bidirectional cards because otherwise one of the cards will show the image in the front, which leaks information and makes the flashcard useless.
