                1. Move mouse to the TextArea.
                2. Press the left mouse button.
                3. Drag mouse to the list.
                4. Release the left mouse button.

                The mouse cursor should appear as an I-beam cursor
                and should stay the same while dragging across the
                components. Once you reach the list, release the
                left mouse button. As soon as you release the left
                mouse button, the cursor should change to a Hand
                cursor. If true, this test passes.

                The test fails if the cursor updates while dragging
                over the components before releasing the left
                mouse button.
