Conversation doesn't show attachments

[Thra11]

If you touch on a toot to view the conversation, it will show attached images for the toot you touched, but not for any of the replies or toots which the toot you touched replied to.

To reproduce:

1. Find a toot with an attached image which has at least one reply.
2. Touch on the toot (the body of the toot, not the image, or the user avatar, or any hashtags or links) to view the conversation around it. You should now be able to see the reply, but can still see the images in the original toot.
3. Touch on the reply. You are now viewing the conversation around the reply, i.e. same chain of toots, but different 'focus'. The original toot is visible, but the attached image is not.
