Description

The elements in the Source mapping area (only this case) are hidden under an expandable element without any name. The "noname" element should not be there - it's confusing.

Other complication is the element doesn't have an id attribute value which makes automated testing difficult. All other named elements have their id values.

I suggest removing this element and make the underlying list visible by default.
