Hover label disappear after dragging axes on this graph

See report https://community.plot.ly/t/tooltip-is-not-showing-when-we-move-y-axis/3387

To reproduce:

• go to https://jsfiddle.net/1yLavejg/30/
• drag any axes
• hover over data, hover labels don't show up.

Looks like the problem is only showing when one axis has fixedrange: true.
