Used to be able to search or open “table of contents / outline” and then when you clicked on your selection in the sidebar or on the page the sidebar would be minimized / in the background. The first pic the sidebar is open and to visualize the entire page you now have to tap on the search/table on contents icon at the top to minimize and see the entire page. The other 2 uploads is a previous search where you clicked on your selection in the sidebar and then you could click on the page to minimize the sidebar and see the entire page
