| <!-- This test checks whether we compute pointer coordinates correctly for the |
| dragstart, dragend, and drop events issued during drag-and-drop operations. |
| This test uses nested iframes, because they are a tricky case when |
| computing the clientX, clientY values from screen coordinates. Furthermore, |
| running this test through LSAN ensures that we reset the drag state |
| correctly in all the frames. --> |
