Keep the BalloonTip open when the BalloonTip's arrow prevents the cursor from being inside the spawning ToolTipWidget, which triggers the ToolTipWidget's leaveEvent and would previously close the BalloonTip. When that happens track the cursor until it either leaves the ToolTipWidget's bounding box or leaves the BalloonTip and goes back to the ToolTipWidget, and respectively close the BalloonTip or leave it open.
