🐛 Bug Report: Galleries that appear as part of a crosspost don't work

[ButteredCats]

Describe the bug

If a post is a cross post of a gallery no pictures are shown, just a /gallery link that doesn't function.

Steps to reproduce the bug

Visit /r/techsupportmacgyver/comments/1ebzpda/the_charger_for_my_thinkpad_keeps_breaking_at_the/ on your favorite Redlib instance See the /gallery/1ebv4dg link that leads to an error if you click it instead of seeing the gallery from the original post.

What's the expected behavior?

The gallery from the original post appears as normal

Additional context / screenshot

/r/techsupportgore/comments/1ebv4dg/the_charger_for_my_thinkpad_keeps_breaking_at_the/ has the gallery that should be seen as it's the post getting crossposted.
