r194879 <https://bugs.webkit.org/show_bug.cgi?id=152473> introduced the ability for sidebar panels to calculate their minimum widths. This functionality works correctly, but there is an issue when the user switches to a view with the sidebar collapsed and then switches back to the first view. Since the second view essentially had a sidebar width of 0, the first view recalculates the width of the sidebar to its minimum, regardless of how large the user had it before he changed views. It is very annoying to have to keep resizing the sidebar to a larger width, so I think it would be better to have the sidebar's remember their previous width and restore it (clamped to the min/max of the current inspector width) whenever a view changes.
