HI @Jason Sypkens,
I found that at most I can only get the inner html of the webpart in the section.
Regarding section, the official does not provide more attributes for this API for us to use.
And I feel regretful to inform you that it turns out to be a by-design one.
And I noticed that some end users have also proposed the same request, it is highly recommended that you can vote this ticket. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding.
