Also, I couldn't test it on the demo site as you don't have a Help forum there.
When you change solutions, a popup overlay appears quoting the content that was the previous solution and asks if you want to change it to the new solution. The quoted text that's in the overlay is not styled (in our case on a dark style, the text was dark on dark whereas the original content being quoted was light on dark).
