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

Look at the map on
https://hu.wikipedia.org/wiki/A_Portland_Streetcar_k%C3%B6rj%C3%A1ratai?useparsoid=0
and
https://hu.wikipedia.org/wiki/A_Portland_Streetcar_k%C3%B6rj%C3%A1ratai?useparsoid=1

What happens?:

The colors on the legend are not displayed on the Parsoid version.

What should have happened instead?:

The legend colors should be displayed on the Parsoid version.

Other information (browser name/version, screenshots, etc.):

I noticed that while deploying Kartographer+Parsoid support; this is not fixed by activating the Kartographer+Parsoid support.

(If anything: adding the Kartographer+Parsoid support seems to remove the squares containing the legend colors)
