It would be fantastic if we also had a UI Test that matched the example provided in the description, it could even be a second one that covers #19950, that is, different icons and text being displayed. As seen below, it looks like the test is checking if one icon set on one page is persisting across the others.

@kubaflo @PureWeen do we still need this now we merged #16796?

[kubaflo]

@jfversluis yes, I don't think we need it anymore. Therefore, I'm closing this pr :)
