📝 Provide detailed reproduction steps (if any)
If you set border bottom to a list item, the Microsoft Word wraps the element using div below:
<div style='mso-element:para-border-div;border:none;border-bottom:solid #A7A9AC 2.25pt;
padding:0in 0in 1.0pt 0in'>
It makes the lists separated by div wrapper, which shows only border. We decided to move border to children and get rid of such wrapper to make list continuation looking better.

✔️ Expected result
The Microsoft Word DOCX mso-element: para-border-div wrapper should not wrap all children. Depending on border direction - it should be moved to first or the last block element inside the wrapper.
❌ Actual result
It's being wrapped.
