HTML sanitation rules applied to HTML in submission body

Question

What are the HTML sanitation rules that get applied to HTML specified in the "submission[body]" parameter for assignment submissions via the Canvas API? The Canvas API documentation on submitting assignments states:

Note this HTML snippet will be sanitized using the same ruleset as a submission made from the Canvas web UI.

I have successfully submitted assignments containing an HTML body via the Canvas API, but I have not been able to locate the mentioned 'ruleset' to determine what types of HTML (and embedded styling) I'm able to send without it being lost.

Could it be the same ruleset that is on the Canvas HTML Editor Whitelist? If the API is a less GUI way of doing things inside Canvas, it would make sense.
