Browsers already have built-in mechanism to prevent flicker while switching pages, unless your page has issues such as flash of unstyled content or something similar.

Yeah you are right. I can't reproduce it at the moment. Maybe I am thinking of a couple of years ago when the browser did in fact flash for the same.

I think scroll position is the one that is not preserved.
