attachments macro does not display properly in comment field

I went through this issue this morning, and I guess this is a pretty recent bug as I use that macro quite often.

This is about the attachments macro when inserted into a comment field below a page.

We run Confluence OnDemand.

How to reproduce the bug:

1. Create a comment on any page.
2. Enter macro Attachments.
3. Save the comment.

The words "Drag and drop to upload or browse for files" is displayed below the dotted rectangle instead being displayed in the middle of this rectangle.

This is hiding the functions "Reply, Edit, Delete, Like" and the date/time of the comment that normally goes with each comments. See picture attached.

This bug happens only in the Comment field. It does not occur when inserted on the main page field.
