**Steps to replicate the issue** (include links if applicable):
Check

vs

**What happens?**:
The Parsoid version shows all the <span> markup instead of colored text like in the legacy parser version.
**What should have happened instead?**:
It's not clear to me that this markup is actually valid, but since it does work with the legacy parser, there's probably something to be done there.
