When creating an interactive map I need to enlarge the selected object when I hover over.
CSS rules execute this part of the task.      
Next, I needed the enlarged object to always be higher than the rest of the map objects.
Javascript does this part of the task.    
Everything works fine in the Chrome browser.
Hovering and zooming with CSS rules does not work in Firefox and the selected object does not pop up. 
I would be very grateful for any idea to solve this problem.
document.querySelectorAll('path.state1').forEach(path => {
  path.addEventListener('mouseover', e => {
    path.parentNode.parentNode.append(path.parentNode);
  });
});
.state1 {
fill:white;
stroke:dodgerblue;
transform-origin: center center;
transform-box: fill-box;
transition:  1s;
}
:hover.state1 {
 fill:dodgerblue;
 stroke:white;
 stroke-width:2px;
 filter:url(#dropshadow);
  -webkit-transform: scale(1.5);
 transform: scale(1.5);
 
 }
