User level: Level 1 (12 points)When reading a PDF document using Preview, I prefer not using the sidebar. But the app constantly keeps reopening the sidebar every 30 seconds, even when I hide it immediately. The option "Always shows sidebar" is turned off. When the app automatically does this the app icon in my dock makes a single jump.
How does this stop?

I'm using macOS Sequoia as well but I do not see a "Always shows sidebar" option anywhere (neither in Preview > Settings or in the menu bar).
The way I hide the sidebar is by clicking View > Hide Sidebar. (To show it again click View > Thumbnails or any other options below "Thumbnails".) Hiding the sidebar this way persists when you reopen Preview.
