OK, I found an issue without involving adoptNode api.

create a test.html file with following content

<!doctype html>
<html>
<body>
<template id="a">
<p>1</p>
</template>
</body>
</html>

Open it in Safari 16+.
Try in console:

> var d = document.querySelector('#a')
< undefined
> d;
< <template id="a">…</template>
> d.content
< Template Content
> d.content.ownerDocument
< #document
> d.content.ownerDocument.documentElement
< null

Should not every node in this static html file have ownerDocument pointing to the document itself??

The null ownerDocument.documentElement seems not right for the content of HTMLTemplateElement.
