Track changes to original class/id names in source-maps?

[soluml]

Feature Request: It'd be great to see the original class/id name in dev tools for easier lookup. I hash all my classes, so class name's like .logo become .A upon build. .A is also currently being used in the source-map and while the line number and file are correct (so it's easy enough to find) it'd be great to see the original class name here.
