Content Delivery API removes LinkItemCollection internal link remaining URL

LinkItemCollection UI allows users to set "remaining URL" on internal pages. But the API removes it. The problem seems to be in  EPiServer.ContentApi.Core.Serialization.Models.LinkItemNode.

Basically if it can get IContent out of the HREF it will get a new HREF using UrlResolverService.

IContent val = UrlResolverExtensions.Route(_urlResolver.get_Service(), (UrlBuilder)(object)new UrlBuilder(href));
if (val != null)
{
  ContentLink = _contentModelService.get_Service().GetContentModelReference(val);
  Href = _urlResolverService.get_Service().ResolveUrl(val.get_ContentLink(), null);
}
