[question] admonition-block inconsistency: tip & info vs others

[koiuo]

TIP and INFO admonition blocks use <aside> as an outmost enclosing element.
The other admonition blocks, CAUTION, IMPORTANT and WARNING, use <section> for the same purpose.

Both use the same CSS class, so this is not an immediate issue.

Is there a reason behind the inconsistency or is it just an oversight?
