This test is only relevant on platforms where it is possible to switch applications in mid-drag (eg. alt+tab, dragging over taskbar buttons, dragging between restored windows).
This testcase requires an external application that accepts dropping of HTML from other applications - eg. Google Chrome and Internet Explorer (not Firefox). Load the helper file in the external application.
Drag this paragraph to the other application and release it. De-select the text in that application if it is selected. Pass if "Pass if this text is on a green background" appears in the other application, and if it has a green background, and if the drag placeholder disappears when the drag is released.
Disable JavaScript in this browser and repeat the test. Pass if the entire dragged paragraph appears in the other application. Vendors may optionally choose to ignore this requirement.
