Custom CSS for document-backlinks-container but only at document root?

When I’m zoomed to the root of the document I get a billion backlinks because I write links to search queries a lot, and dynalist treats them all as links to the root of the document for some reason. Any way to hide document-backlinks-container completely when zoomed to the root but otherwise show it?

Basically I am trying to fix this bug myself just in case it never gets fixed or is a feature. Top node of document shows all search query links as backlinks
