Tooltip problem with variation slider in products list

Hi,
With the last version of the plugin, I have a tooltip show problem on hover.
When colors variations are showing not in slider, the tooltip appear.
But when the slider is showing, the tooltip is not showing.
Please find 2 examples in attachment.
In these 2 examples, the mouser pointer is on the variation image.
Left image, hover tooltip is okay. Right image, not.
Thank you.
