The selected item SVG must rise above the other items

Question

Question inspired while writing this answer.

It is necessary that when you hover over one of the map regions, it will increase in size and be higher than other elements.

Vertical positioning follows the principle - which element in the code is written last, the one above.

Below is an example demonstrating this problem:

.state {
fill:white;
stroke:dodgerblue;
transform-origin: center center;
transform-box: fill-box;
transition:  1s;
}
:hover.state {
 fill:orange;
 stroke:white;
 stroke-width:4px;
 -webkit-transform: scale(1.5);
 transform: scale(1.5);
     }

@Alexander Nied Thank you for the link I will study. But I would like a specific solution for this example — Alexandr_TT, Aug 20 '19 at 19:01
The method in [this answer](https://stackoverflow.com/a/47298845/924299) seems to [work pretty well](https://jsfiddle.net/xa6y9n8v/). — showdev, Aug 20 '19 at 19:32
@showdev Great answer. I understood how this is done. Post your answer here and I will be happy to accept the answer — Alexandr_TT, Aug 20 '19 at 19:38
I would use javascript. On mouse over you `appendChild()` the hovered element. Please take a look at this pen: https://codepen.io/osublake/pen/YXoEQe?editors=0010 — enxaneta, Aug 20 '19 at 20:05

Thank @enxaneta for help. It was through his link that I selected and finalized the solution.

var svg = document.querySelector("svg");
var paths = document.querySelectorAll("path.state");

var i = paths.length;
while(i--) {
  paths[i].addEventListener("mouseover", function(e) {
    svg.appendChild(e.target);
  });
}

Below is the full code:

var svg = document.querySelector("svg");
var paths = document.querySelectorAll("path.state");

var i = paths.length;
while(i--) {
  paths[i].addEventListener("mouseover", function(e) {
    svg.appendChild(e.target);
  });
}

.state {
fill:white;
stroke:dodgerblue;
transform-origin: center center;
transform-box: fill-box;
transition:  1s;
}

:hover.state {
 fill:blue;
 stroke:white;
 stroke-width:4px;
 -webkit-transform: scale(1.5);
 transform: scale(1.5);
 
 }
