Content width doesn't always shink when tab sidebar is active
Sometimes, when I have the tab sidebar active while using this extension, the width of the browser's main content does not shrink according to the vertical space being occupied by the sidebar. This usually means that content will overflow out of the window on the right and a horizontal scrollbar appears.
This issue is weird, it doesn't happen on every page. For example, I run into this problem on the Google search results page, but not in this Gitlab instance (the content shrink and other aspects of the page behave as if I had actually resized the browser window smaller, such as the menu collapsing into a mobile-friendly UI).
Let me know if there's any debug information I can provide. Thank you.
