<aside>s that are taller than the paragraph that they are beside use vertical space in the main text

Maybe this is intentional too? But I don't think aside that span two paragraphs look bad.

As a quick hack, I added

@media(min-width:768px) {
    aside {
        margin-bottom: -500px;
    }
}

I guess this could lead to problems with consecutive asides? But those don't look good, so I'm not too worried.

Yes, this is a consequence of using CSS grid for layout.

This hack works great for computers, but it messes things up with mobile phones.
