-`document.querySelector('script[type="text/html"]')` has exactly one child node and it's a text node.
## Comments
If there is one or more `<script>` inside an HTML comment before any `</script>`, the first `</script>` will not end the main script.
### Examples
Ending tag inside comment works because there are no nested script tags.
```html
<scripttype="text/plain"><!--
</script>
```
There is a nested tag but it doesn't need to be closed because it's treated as text.
```html
<scripttype="text/plain">
<script>
</script>
```
There is a nested tag but it doesn't need to be closed because it's not inside an HTML comment.
```html
<scripttype="text/plain">
<script><!--
</script>
```
There is a nested tag but it doesn't need to be closed because main closing tag is not inside an HTML comment.
```html
<scripttype="text/plain"><!--
<script>-->
</script>
```
The main closing tag is in a HTML comment but still works because there is no `<script>` before it in its comment (there is one in the previous comment).
```html
<scripttype="text/plain">
<!--<script>--><!--
</script>
```
There is a nested tag and it's in an HTML comment but it doesn't need to be closed because it's not `script`.
```html
<scripttype="text/plain"><!--
<div>
</script>
```
First closing tag is inside a comment with one or more previous opening tags so it doesn't close main script tag.
```html
<scripttype="text/plain"><!--
<script>alert();</script>
</script>
```
There is a nested tag and it needs to be closed because it's in a comment `script`. The amount of `<script>` doesn't matter.
