Ignores mouse motion events when mouse is pressed or drag and drop is in progress in TooltipController to prevent scroll jankiness. The tooltip should be hidden in those cases anyway and we can skip early. This improves scrolling and dragging content, notably with sites like Google maps or sites that use pointer lock such as http://media.tojicode.com/q3bsp/. It also seems to fix laggy text selection in omnibox (tried before and after the patch.
