Maybe call this reset_by? resets sounds to me like it might be the dd/dt that's doing the resetting of dl, rather than the other way around.

I'm not sure if I understand the test to it's full extend, but since quite some time divs are allowed as children of dl: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/dl#wrapping_name-value_groups_in_div_elements

If I misread the test I apologize for the noise 😊

The div could also be a span, it doesn't matter, the rule is "there has to be a dl in-between, and it's not in that case so we issue the error. You can test yourself by pasting that html into the browser and see how it "repairs" it
