Hi Team,

While going through Blink's commit, I came across a test case where all browsers differ:

Test Case - https://jsfiddle.net/ckqy396n/

Blink's Commit - https://chromium.googlesource.com/chromium/blink/+/806c35622c8a96348b269aa00e00b3f5c4648709

*** Safari Technology 159 & Safari 16.2 ***

document.documentElement.outerHTML: <a></a>
document.childNodes.length: 2
b element: [object HTMLElement]

*** Chrome Canary 110 ***

document.documentElement.outerHTML: <a></a>
document.childNodes.length: 1
b element: null

*** Firefox Nightly 110 ***

Nothing - Nada... No output / alert etc

Just wanted to raise this bug to get input whether there is something to fix here or raise web-spec clarification.

Thanks!
