Progress dot "unanswered" instead of "answered" in "show solution view"

[pixelhexe]

After click on "finish" and "show solution" the last dot of the progress bar has always CSS class "unanswered" which should be "answered" (it controls the color of the dot and irritates a little). Only after navigating to the last dot (in this "show solution view"), everything is fine (last dot classified as answered).
You can see it here as well:
