Background image layout is not working with the New Email Designer

Do we have any updates on the background images layout with the new email editor? I've noticed an issue: when I try creating a text component, the editor provides an option to add a background image URL, but this doesn't work in Outlook—the image simply doesn't appear. If I create this section using custom HTML instead, the code becomes too confusing for non-technical users to update the image.

If this makes sense, could we implement a feature for variables? For example, if I use custom HTML, could there be a way to add variables so that others can easily update them without needing to modify the HTML code itself?
