debugging with devel is difficult due to no visual indication of hierarchy via dpm()/krumo.

In _messages.scss the "&.messages ul" sets padding to 0, but krumo relies on padding-left on ul elements to indicate hierarchy.

Removing the padding declaration resolves the krumo issue, but likely creates others. The comment says "Styles for multiple lists in Status Message" that's a bit vague to me, but maybe indicates we could more narrowly target that selector to specifically nested lists. Not sure on that though.
