In full-screen Safari 13.0.5, when I move my mouse cursor to the left of the window, a sidebar slides out showing my reading list and bookmarks.
Often I was intending to click something at the left of the window, or just accidentally moved my cursor there. Then the slideout ends up interrupting my action or blocking my view of the web page.
How do I stop this sidebar from appearing when my mouse is at the left of the display?
This upvoted answer for macOS El Capitan (apparently) doesn't work for me.
