Max height for posts on UserPostsPage

I find a problem when I post a very long post, then open my Profile page(link below), it takes a lot of space. So I think it should be a thumbnail.
Look at this page, https://discuss.flarum.org/u/vinkenvvt, the first long post takes the whole space. :)

Start by locating the UserPostsPage implementation and reproduce the behavior using the linked profile with a very long post. Determine how post previews are rendered, then verify that long posts are constrained to a thumbnail-sized area while normal profile activity remains usable.
