Datatable Row Reorder not working with child rows at the bottom.

Hello!

Im trying to create a table with child rows and row reorder combined. Everything works, until the last row as a child element.

When the last row contains a child row, row reordering doesnt work anymore.

I have a working example here -> using jQuery 3.3.1:

Thank you in advance!
