Why in react, when navigating through pages, do they come off from the bottom?

Question

React

that is, if I go down on the main page and click on the link there, then a new page will open and screen will be at the bottom of the page? Is this because of the spa or can it be fixed?

Answer 1

It shouldn't be like that, make a demo on github to understand better.
ps to the extreme, if everything is bad, you can always use window.scrollTo
