useEditorPortalHost

Where floating layers are portalled to.

SEMANTICS-ASSUMED: the host is the container itself rather than a dedicated child node. Portalling into the container keeps a menu inside the editor's stacking and theming context (the CSS custom properties are set on the container), which is the property that makes portalling worth doing at all; a separate host node would have to be created and torn down in lockstep with the container for no additional benefit.
