Collapsed borders paint a shared edge once, so the spacer <tr> bridging the gap took the row separator with it and left one fragment open — visible in a fixture as tables missing their frame on a page. The spacer now draws the line LibreOffice draws there: the separator the break falls on, or the table's own box where the rows carry none. Absolutely positioned, since a collapsed border on the spacer shifts every row below by half.
