When navigating "Back", in the browser, the previous page starts at the beginning.

If you scroll down on any page of ChainBB, then click into a forum or thread, and then go back to the previous page, the app reloads the content, and never scrolls the browser window down for you.

This occurs in all browsers I've tested. Safari (iOS and macOS), Firefox, and Chrome.

You can see an example in my gif. I start off on the main page of ChainBB, scroll down, and then click into the announcements forum. Notice how when I click the browser back button, the page is loaded and the page remains at the top, instead of auto scrolling/jumping down to where the link to the announcements is.
