这是如何停止 <div> 标签干扰计数器的扩展？

接受的答案解决了一级标题的问题（即问题中的 H1），但如果有多个级别的标题则不能解决（见下文）

body {
  counter-reset: h1 h2 h3 h4;
}
h1 {
  counter-reset: h2 h3 h4;
}
h2 {
  counter-reset: h3 h4;
}
h3 {
  counter-reset: h4;
}
h1:before {
  counter-increment: h1;
  content: counter(h1)"  ";
}
h2:before {
  counter-increment: h2;
  content: counter(h1)"." counter(h2)"  ";
}
h3:before {
  counter-increment: h3;
  content: counter(h1)"."counter(h2)"."counter(h3)"  ";
}
h4:before {
  counter-increment: h4;
  content: counter(h1)"."counter(h2)"."counter(h3)"."counter(h4)"  ";
}
div:before {
  content: counter(h1)"."counter(h2)"."counter(h3)"."counter(h4)"  ";
}
<div>
  div
  <h1>H1</h1>
  <h2>H2</h2> 
  <h3>H3</h3>
  <h4>H4</h4>
  <h4>H4</h4>
  <h4>H4</h4>
</div>
<div>
  div
  <h4>H4</h4>
  <h4>H4</h4>

</div>
<div>
  div
  <h3>T1</h3>
  <h3>T1</h3>	
</div>
从上面的片段可以看出，并不是所有的计数器都是在 div 之间继承的。有没有办法来解决这个问题？

我的解决方案：

代替：

h1{counter-reset: h2 h3 h4;}
h2{counter-reset: h3 h4;}
h3{counter-reset: h4;}

和

h1{counter-reset: h2 initial h3 initial h4 initial;}
h2{counter-reset: h3 initial h4 initial;}
h3{counter-reset: h4 initial;}


body {
  counter-reset: h1 h2 h3 h4;
}
h1 {
  counter-reset: h2 initial h3 initial h4 initial;
}
h2 {
  counter-reset: h3 initial h4 initial;
}
h3 {
  counter-reset: h4 initial;
}
h1:before {
  counter-increment: h1;
  content: counter(h1)"  ";
}
h2:before {
  counter-increment: h2;
  content: counter(h1)"." counter(h2)"  ";
}
h3:before {
  counter-increment: h3;
  content: counter(h1)"."counter(h2)"."counter(h3)"  ";
}
h4:before {
  counter-increment: h4;
  content: counter(h1)"."counter(h2)"."counter(h3)"."counter(h4)"  ";
}
div:before {
  content: counter(h1)"."counter(h2)"."counter(h3)"."counter(h4)"  ";
}
<div>
  div
  <h1>H1</h1>
  <h2>H2</h2> 
  <h3>H3</h3>
  <h4>H4</h4>
  <h4>H4</h4>
  <h4>H4</h4>
</div>
<div>
  div
  <h4>H4</h4>
  <h4>H4</h4>

</div>
<div>
  div
  <h3>T1</h3>
  <h3>T1</h3>	
</div>
