Details

STR:

1. Load the URL
2. Open DevTools and do

document.documentElement.firstChild.attachShadow({mode:'open'}).innerHTML = '<slot />'

which attaches a shadow root on the <div> and put "<slot />" into its innerHTML.

Expected:

1. <span> is rendered inside the Shadow DOM because there is a <slot />.

Actual:

1. It didn't and the page is blank.

Note:

I am sure the same HTML document works, like

data:text/html,<body><div><span>cheese</span></div></body>

with

document.body.firstChild.attachShadow({mode:'open'}).innerHTML = '<slot />'
It works if you do:
> document.documentElement.firstChild.attachShadow({mode:'open'}).innerHTML = '<slot xmlns="http://www.w3.org/1999/xhtml"/>'
Nice catch! Thanks.
