Table of content on top of content when sidebar is open

[julia-rabello]

Describe the bug
When navigating to a tutorial by using the sidebar, the table of content appears on top of the content depending on the size of the screen.

To Reproduce

Navigate to an article using the sidebar.

Expected behavior
The table of contents should be hidden when the sidebar is open and the viewport is not sufficient to accomodate it without rendering it on top of the content. It should only appear when the sidebar is collapsed in these cases
