88 <p id="description">This test can be used to verify that the not-allowed cursor is shown during an invalid drag-and-drop operation.
89 In particular, if the effectAllowed is <code><script>document.write(ALLOWED_EFFECTS)</script></code> and the dropEffect of the
90 drop target is <code><script>document.write(DROP_EFFECT)</script></code> then the drop is not allowed and the cursor should
91 change to the not-allowed cursor. Note, this test only pertains to the Windows build since the Mac build does not show a drop cursor
92 for a not-allowed drop operation (see bug #25925).
94 Drag the red square over the drop target (demarcated by the dashed boundary). While hovering over the drop target, if the cursor
95 is <img alt="not-allowed" src="data:image/gif;base64,R0lGODlhEgASAIAAAAAAAP///yH5BAAAAAAALAAAAAASABIAAAIvjA+px6ifmnmM1ijDmlbuuHmAhoWXaTqYKq7sObZw3HwgXd8cPr8yDGxBXEJioAAAOw=="> then the test <span class="pass">PASSED</span>. Otherwise, the test <span class="fail">FAILED</span>.</p>
