https://commits.webkit.org/310936@main refactored `WI.DOMTreeElement` to consolidate creation of badges per layout flag and added an assertion for an unknown badge type. There is a layout flag, `WI.DOMNode.LayoutFlag.Rendered`, for which there is no badge (this is used to dim not rendered DOM nodes in the DOM tree, for example `display: none` nodes). The assertion is unintentionally tripped.
