Comment 2 for bug 1946619

Point 1 from above has been confirmed today - changing the icon for 'Return to pages and collections' to layer-group: https://fontawesome.com/icons/layer-group?s=solid. Kristina and I also decided to change the icon for the 'Pages and collections / Portfolios' page to this icon, as it more accurately reflects the nature of the content on that page.

Point 2 is a separate issue that has been discussed today and reported separately here: Bug 1982298
