-/**
- * This class is used to control the document focus when a non-body element contains the main scrollbar.
- * Web browsers will not automatically focus a custom element with the scrollbar on load, which results in
- * keyboard shortcuts (e.g. arrow keys) not controlling page scroll. Instead, this class will manually
- * focus a dummy element inside the main content, which gives keyboard scroll focus to that element.
