1. Open a project.
2. Right-click on some symbol and select "Refactor" -> "Rename Symbol Under Cursor" from the context menu.
   A new view shows up below the editor. This is much wider than the other views. In some cases this squeezes the side bar (e.g. Projects view) to the window border. Even when selecting a different view the minimum width persists until the search from step 2 is being cleared.

Please rearrange the "Rename Symbol Under Cursor" view so it does not need that much horizontal space.
