Content in drop down / accordion (collapsible and extendable) format and nested content

In Service Now it is possible to structure knowledge articles in sections which you can collapse or expand / accordion format.

There may for example be instructions which are written in the extendable sections, but we are not sure if the assistant can ingest and use that information.

I was looking for official information on the Moveworks docs to cover the expanded / collapsed content topic but could not find yet.
Do you have a reference to point me to, or can you confirm if there are any limitations regarding this?

With the HTML-based articles we’ve seen that the information contained in the collapsible part is being found by the Assistant. Is this because it’s HTML or because extendable sections are readable?

We were also reading into the nested content docs but not sure if from a Moveworks perspective accordion formatted content is considered nested content?

An overall limitation guide when it comes to ingesting content in Moveworks would be great instead of needed to check specific topics in the docs. 

Thanks in advance for the help!
