You can add the code after line $box.on('mousemove', onMousemove);
$box.on('mouseout', function () {
onThumbLeave();
isOverThumb = false;
$largeWrapper.addClass(MagnifyCls.magnifyHidden);
});
I am using 2.2.6 and still having this issue
Two new installs of 2.3.0. And the issue is still there on both sites.
