Describe the bug

context
I open https://sphinx-book-theme.readthedocs.io/en/stable/tutorials/get-started.html#add-a-source-repository-button-to-your-theme or press "Add a source repository button to your theme" content button on https://sphinx-book-theme.readthedocs.io/en/stable/tutorials/get-started.html.

expectation
I expected content section on the right panel to change to "Add a source repository button to your theme".

bug
But instead it tells me that the previous section is active.

If I scroll down a little bit, then the section is correct.
