Unable to share "self" links, aka those without an external URL

[mdaniel]

This is with HN 2.1.5 on Android 4.1.2

1. Search for a "Who is hiring" thread (or one of the "Ask HN" posts)
2. Use either the main-menu share button (hidden under the long-tap of the article headline) or click into the thread, wait forever for it to load all 500 posts, then tap the share button
3. Choose your favorite app, either Gmail or Keep or whatever
4. Observe that the title of the article is shared, but not the link to HN
