chrome://flags/#omnibox-ui-max-autocomplete-matches doesn't work?

[patrickdrd]

even though I've got chrome://flags/#omnibox-ui-max-autocomplete-matches set at 12 (max),
it doesn't work, I only get 3 bookmark suggestions on the address bar,
I don't think it's a cent issue, but I thought about asking here,
does anyone know if there's a way to make it work?
