Prevent TOC Sidebar from Auto-opening on large monitors?

I'm using a Table of Contents with The canned Qualtrics themes "Minimal - Blue" and/or "Blank (For Styling)." I have the TOC sidebar enabled. When users view the survey with large monitors, the sidebar automatically opens after a block loads, even if the user previously closed it. This is disorienting. Is there script I can add that will keep the sidebar always closed unless the user manually opens it by clicking the sidebar (hamburger) button?
