Can the Home Route or Canonical URL be used in SEO tags?

[pierslawson]

I've noticed that when I generate the URL of a Content Item that happens to be the Home Page then the URL generated includes the permalink for the page. This then flows into other uses of the URL such as when the SEO module creates the "og:url" property or the "twitter:url".

<meta content="https://localhost:44300/home-page" property="og:url" />
<meta content="https://localhost:44300/home-page" name="twitter:url" />

I thought I could override this behaviour by turning on the SEOMeta Part for the Content Type used for the home page and providing a Canonical URL for the Content Item that is being used for the home page. That causes the link rel "canonical" to be added and set correctly but not the other tags:

<meta content="https://localhost:44300/home-page" property="og:url" />
<meta content="https://localhost:44300/home-page" name="twitter:url" />
<link href="https://localhost:44300/" rel="canonical" />

I have the Base URL set to https://localhost:44300/
I have the Home Route and SEO features turned on.
I have the Autoroute part in the Content Type of the Content Item that is the home page
It doesn't appear possible to set up a page to be the home page without Autoroute nor with Autoroute and a blank permalink

Am I missing somthing obvious here?
