live_redirect does not remember scroll position if a live_patch is done before it

[dvic]

Environment

• Elixir version (elixir -v): 1.13.4
• Phoenix version (mix deps): 1.6.10
• Phoenix LiveView version (mix deps): 0.17.10
• Browsers you attempted to reproduce this bug on (the more the merrier): chrome, firefox, safari
• Does the problem persist after removing "assets/node_modules" and trying again? Yes: yes

Actual behavior

setup: liveview A and liveview B

SITUATION 1

1. load liveview A and scroll down
2. cilck on a live_redirect to liveview B
3. browser back returns to original scroll position of liveview A

SITUATION 2 (same as SITUATION 1 but with a live_patch in between)

1. load liveview A and scroll down
2. do live_patch, scroll more down
3. cilck on a live_redirect to liveview B
4. browser back does not return to original scroll position of liveview A

Expected behavior

I did not expect that a live_patch before a live_redirect would change the way the back button works w.r.t. the scroll position.

Is this intended behavior or a possible bug?

Actual usecase:

List view of items with a "load more button" (which is the live_patch), I'd like to be able to click on one item (liveview B) and go back to the original position in the list.

If it helps, I can make a repo that reproduces this.

Here is the repo that reproduces this: https://github.com/qdentity/lv_reproduction_repo/tree/scroll-bug

and here is a video that shows that the scroll position is lost after "load more" is clicked (which is a live_patch):

Just checked if #2097 fixed this issue: it does not 🙁
