Displayed domain on certain posts is incorrect

On certain posts, the displayed domain in parentheses is reddit.com even when Post Properties has a URL with a different domain.

Based on a sample of size two, this seems to be the case for posts that Old Reddit (on a web browser) is able to display as an embedded album (via preview.redd.it), but which are actually linked to an external (non-Reddit) domain.

It should be noted that Old Reddit also incorrectly shows reddit.com in these cases. If indeed it is the Reddit API that is supplying an incorrect domain, then it would be good if RedReader does its own parsing to determine the correct domain based on the actual link URL. (The goal is to avoid unexpected redirection to facebook.com, for example.)

Examples:

Post link	RedReader post screenshot	RedReader properties screenshot	Old Reddit screenshot
103iu5b
192tk1z

Above RedReader screenshots are for RedReader v1.22, and the observed behaviour persists to v1.23.1.

Reproduce the incorrect domain using the linked Reddit posts 103iu5b and 192tk1z, then trace the post display and Post Properties entry points that consume the URL. Compare the displayed domain with the external link's actual host; done means both examples show the correct domain and do not suggest an incorrect redirection target.
