drag and drop - dragging plain text onto the OS

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 text from other applications - eg. Wordpad (write.exe) on Windows. Ensure that the external application is open.

Drag this paragraph to the other application and release it. Pass if "PASS" appears in the other application, and the drag placeholder disappears when the drag is released.
