/**
 * Contribution that tracks `mouseup` and `mousedown` events.
 *
 * This is required to be able to track the `TabBar`, `DockPanel`, and `SidePanel` resizing and drag and drop events correctly
 * all over the application. By default, when the mouse is over an `iframe` we lose the mouse tracking ability, so whenever
 * we click (`mousedown`), we overlay a transparent `div` over the `iframe` in the Mini Browser, then we set the `display` of
 * the transparent `div` to `none` on `mouseup` events.
