Brave jumps to top of the page after after go back to my local HTML page

I got a long LOCAL HTML-Text List with Links.
If i click a link in the middle of the page to an online page and then click backward, then the browser jumps most times to the top of the page, instead of stay in focus of the last viewed link.
This does not happen on online pages, only with local pages.

Is this a browser error?
Or could i do something in my HTML ?
