When using a SelectionRectangle to provide drag-based selection for a TableView, it will filter and handle certain input events that it should not, primarily when using things like dialogs placed over the TableView. See the attached example, which creates a TableView with selection enabled. When clicking on "Open Dialog" it will open a dialog with a ListView inside it, which cannot be dragged to scroll it. Instead, if you drag far enough, you'll see the underlying table be selected through SelectionRectangle.
