Issue with current documentation:

At https://numpy.org/doc/stable/reference/arrays.indexing.html, for instance, if you scroll down on the page, the sidebars scroll with the content, and stop being visible. This particularly defeats the purpose of the right sidebar, which is supposed to show you which section you are viewing.

Compare this to the NEPs documentation, e.g., https://numpy.org/neps/nep-0021-advanced-indexing.html, where the sidebars are pinned to the page.

It's not clear to me why this happens. I think both documents are using the pydata Sphinx theme

Idea or request for content:
