Preserve scroll position on body

[MartinSStewart]

While using the Elm plugin for Parcel I've noticed that whenever the page I'm working on hot reloads, any scroll offset on the body gets reset. This is a problem as the time I spend scrolling back to where I was on a long page can add up.

I'm posting this issue here because, as I understand it, the Elm plugin for Parcel relies on elm-hot for hot reloading.
