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 allows dragging of selections into other applications - eg. Wordpad (write.exe) on Windows. Ensure that the external application is open.
Move the browser window so it sits about 200 pixels down from the top of the screen.

Pass if the text you selected appears in the input.
Subtest 2. Select the text in the external application, and drag the selection into the following block: Pass if the text you selected appears in the block.
