        1) The test contains a drop-aware panel with a red background.
        2) Open some page in a browser, select some text.
           Drag and drop it on the red panel.
           IMPORTANT NOTE: the page should be stored locally.
           Otherwise for instance Internet Explorer may prohibit drag and drop from
           the browser to other applications because of protected mode restrictions.
           On MacOS do NOT use Safari, it does not provide the needed DataFlavor.
        3) Check the data in the output area of this window.
        5) The output should not contain information that any of
           flavors is not present in the system clipboard.
        6) The output should contain data in three different formats
           provided by the system clipboard.
            - Data after the "ALL:" marker should include the data
              from the "SELECTION:" marker".
            - Data after the "FRAGMENT" marker should include the data
              from the "SELECTION:" marker and may be some closing
              tags could be added to the mark-up.
            - Data after the "SELECTION:" marker should correspond
              to the data selected in the browser.
        7) If the above requirements are met, the test is passed.
