In this case, the original text is being returned due to this heuristic:
https://dxr.mozilla.org/mozilla-central/source/devtools/shared/inspector/css-logic.js#312

It's not completely clear to me that removing these lines is ok.  Since it's just
a heuristic, it might run into other cases where it was correct to bail out.

The best fix here is described in bug 724505; where I haven't made progress for a long time...

Based on Tom's comment I'm marking this as blocked on bug 724505 and prioritize to P2, just like 724505.
