Read posts don't turn grey until after refresh, and not at all when just viewing image/link.

Describe the bug
A clear and concise description of what the bug is.

After I "read" a post and to back to my feed, I expect the post title to be greyed out to show that I've just read that post. However, the title color doesn't change until after I scroll all the way back to the top of the feed and pull down to refresh.

Also, when only opening the image or website link for a post and not opening the post/comments itself, the post never appears as already read. I feel like that would be the expected outcome, since sometimes I don't feel like reading the comments but still want to know I've already viewed that post's content.

To Reproduce
Steps to reproduce the behavior:

1. Read post.
2. Go back to feed.
3. Notice post still appears as if unread.
4. Refresh feed
5. Notice post now appears greyed out correctly.

The repro is indeed fixed, not sure if we should mark a post as read if you view its image directly from the feed? @twizmwazin what do you think

I think viewing an image or link directly should mark the post as read
