"Show content" doesn't show content

When in my main feed, a post with a content warning has a "Show content" button. When I select that button, however, it does not show the content, it is exactly the same result if I just clicked anywhere else on the post - it moves it to the right-side selected-post view, but still with the content hidden and a "Show content" button.

I think the correct behavior would be just to show the content, inline. There's no reason to think that I will interact with this post and, if I do, I just need to click on the now-visible content and phanpy can proceed as usual.

Here are two screenshots showing the current behavior.



Start in the main feed at the content-warning "Show content" button and trace how selecting it opens the right-side post view. Confirm the current hidden-content behavior, then make the button reveal the post inline without selecting it; done means the content is visible in the feed and normal post interaction still works.
