Why Fasterflect doesn't take several binding flags into account in Property or Get/SetPropertyValue

I have a class hierarchy where I use the new keyword several times due to a good reason. When I try to call GetPropertyValue on a member which is hiding another, then I get an AmbigousMatchException even if I specify ExludeHiddenMembers in the bindingflags. Is this by design? If yes why?

I checked the source code and I can see that it checks for some bindingflags and retrieves all properties if they present, but it doesn't include flags there like ExcludeHiddenMembers, etc. But they would require processing the whole type tree too, so is it a bug then?...

Here is the relevant part:

public static PropertyInfo Property(this Type type, string name, Flags bindingFlags)
{
  // I think here should be the above mentioned flag too
  if (bindingFlags.IsAnySet(Flags.PartialNameMatch | Flags.TrimExplicitlyImplemented))
    return Enumerable.FirstOrDefault<PropertyInfo>((IEnumerable<PropertyInfo>) PropertyExtensions.Properties(type, bindingFlags, name));
  ...
}

Unfortunately as I can see the project seems to be quite dead currently.
