  OS: Windows_NT x64 10.0.19042

Steps to Reproduce:

1. Open https://raw.githubusercontent.com/MsSQLGirl/jubilant-data-wizards/main/Notebook%20Templates/TroubleshootingGuideTemplate.ipynb in ADS.
2. Try browsing to the notebook parts using the links, i.e.
   

Expected:
Users should be able to easily see that the page has scrolled to the target heading / anchor.
For example:
When the ADS Window is maximized:

1. Actual: When users click on "Overview" (because it's visible on the very bottom of the page), users might not realize / easily find where the link goes to. Suggestion: it would be nice to scroll it to the appropriate heading.
2. Actual: When users click on "Risk / Impacts", "Symptoms" or "Mitigation", the page scrolls but the headings are not visible. i.e. scrolled too much that users might find hard to identify which section is referring to the link clicked.
   

When the ADS Window is in a custom size (i.e. not maximized), the experience is different from when the window is maximized.

1. Actual: When users click on "Overview" (not visible on the window, it doesn't go anywhere.
2. Actual: When users click on "Symptoms", the page scrolls but the Symptoms is right in the middle of the window.
   

I commented a potentially related issue #9941 (comment) - where the offset issue is more severe if the text cell containing the links are somewhere in the middle of a notebook.

@chlafreniere @halerankin - would you be able to look into this please? Thank you!

@MsSQLGirl @chlafreniere Just before Christmas, I dedicated an entire day to testing the current experience and to look for possible solutions. So far I have no solutions. I will dive back in.

My PR has one approval so far. We should get this into master ASAP.

@halerankin You should add people as reviewers if you want them to look at it 😄 Many people don't get notified of a PR unless they're added as a reviewer.
