What information was incorrect, unhelpful, or incomplete?

The link in the "Related Topics" sidebar to "DocumentOrShadowRoot" leads to a 404 not found page.

Specific section or headline?

Related Topics sidebar. It looks like this sidebar gets populated by this JSON file:

content/files/jsondata/GroupData.json

Line 1657 in ab7d8de

"DocumentOrShadowRoot",

What did you expect to see?

Either the link should resolve somewhere, or the link shouldn't be present at all if the page truly doesn't exist. It seems that this PR removed the DocumentOrShadowRoot page.

Did you test this? If so, how?

Tested by clicking the link in the browser
