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 the orange block to the other application and release it. Fail if the word "FAIL" appears in the other application.
