PageLayout doesn't extend the sidebar divider when extending the height.

Description

On GitHub, I've seen some pages using the PageLayout component, but there's a problem: when you can't scroll, the PageLayout doesn't stretch to fill the whole page, which means the divider ends up getting cut off halfway down the page. To fix this, I tried making the PageLayout fill up all the available space from its parent in a few instances, but this didn't solve the issue – the divider still gets cut off.
