favorites disappear #1047
Description
There are multiple circumstances in which you favorite a post and then you see the post again and it doesn't look like you favorited it.
For example if you tap on a list in your Home feed to view it, like it and then go back to your Home feed, the star is empty. I just tried it to verify what I was experiencing and it didn't happen, so it must depend on something else, but it definitely happens.
Also when you scroll down far enough in your Home feed it starts repeating posts you've seen (why does it do this?). When a post you've favorited comes up again, it's not favorited.
Also if you're down your Home feed and you tab Home to go to the top of the feed and then scroll back down, some of the posts you've favorited aren't favorited anymore. Again this may rely on something else happening like closing the app and reopening it.
Even though these posts don't look like you've favorited them, you have, it's just not showing. I've verified this by looking at the same post in the browser app.
