  The issue was edge was using zsdch and you were unable to turn off if. MS released an edge version allowing a flag to disable zsdch encoding, then in later versions this flag has been removed, edge defaults to advertising ZSDCH, but will only use it if it is supported e2e. The document was published after MS introduced ZSDCH in previous version of edge.
