In desktop mode, if the sidebar is too wide for the container, this ensures that the sidebar doesn't expand too far, leaving one collapse icon's worth of space in the main area. Which is useful if there are nested sidebars. (Slightly tangential to this PR but I didn't want to forget to fix this.)

I think we should bring back the width: 100%

I checked all of our rules and .sidebar always has both grid-column and grid-row properties, which drive the height and width of the sidebar container. I'm comfortable with both being redundant, but happy to leave width for now if you want.
