It just occurred to me that crossposts sometimes have different body texts and the comments could be in the context of that, and even if we disregard the comments altogether, you might still wanna read the body text. The convenience of having all comments grouped together would mean that no one will go check each crosspost and read its body text, how would you know that there is one anyway?

Maybe there could be a button that shows the body text of each crosspost, either as a popup or a collapsible block
