Comment 4 for bug 1833034

A bug was introduced in this fix which does not allow the user to remove an image from the image artefact.

Steps to reproduce:

- Add an image artefact to a page.
- Select an image and save
- Edit the image artefact on the page
- Try to remove the image

Expected result: image should be removed
What actually happens: image does not get removed due to an error in the console.

I'll add a patch.
