MT throws error when attaching multimedia file containing an "&"

I've been through a it of unintentional testing tonight...

Tried to attach images to MT entries, and found that if the image name contains a "&", such as in "jill & jim.jpg", this image will be correctly attached and displayed in the "old" display layouts.

In the "new", "default" layout, the attempt to attach such a file will cause an error.

If I attach such an image using an "old" layout, it will not display in the "Default layout", but only display the file name with the ampersand escaped ("jill & jim.jpg").

I am using MT 16.2.1.1044.

Would be worth checking if this bug still exists for the up-to-date version of MT. Easy to work around, but puzzling and time-consuming until you found out why it does not work.
