Bugfix/auto scroll to chapter

[Dr-Wade]

There is an annoying bug (not consistent though) where you don't reach the beginning of a chapter when clicking on it in the sidebar (or when loading a given chapter via a link).

This PR fixes this issue.
I also fixed the numbering of the items in the sidebar to be consistent with the chapter ID

Thank you so much for your contribution, Edward!
I've also experienced this annoying bug so I'm very glad someone has finally addressed it. Thanks!

I'm sorry but it's not working fine for me on Desktop. Testing Skjulte Skatter March 2023.
Both the scroll location is wrong and the menu started behaving very strange:

• the chapter id you get in the url is not correct
• you can scroll infinitely the same publication (over and over again)

[Dr-Wade]

Hmm... This is weird, can't seem to reproduce the issue here. Especially, I really can't understand why you would be able to scroll infinitely the same publication.

Can you see any particular error in the console? Also, which language did you use when testing?

[cs1m0n]

I don't get any error message in the console. The language is Norwegian.
The strange behaviour starts after I navigate to a chapter from the menu.
I've sent you a screen recording. You can't see the address bar, but after first choosing a chapter, that id is remembered and whenever I click on chapter 1, I get redirected to the remembered chapter id.
I guess the infinite scrolling is because chapter 1 is redirecting to the remembered chapter id.

I'm not able to reproduce this issue, even when following the exact same step. Maybe we should schedule a session of pair programming, so we can look at it together?
