The default tab interval was fixed at 1.25cm, so a file's own w:defaultTabStop / style:tab-stop-distance was ignored and the DOCX export wrote 1.25 back over Word's 1.27. It is a document setting now. A stop can also carry the character it repeats across its gap. odf-kit has no leader option and mints one automatic style per option set, so the leader rides style:type behind a sentinel — matching on position and alignment alone gave every stop at 6cm the same leader, which LibreOffice drew back plain as day.

// stop at 100mm in a 30mm-indented paragraph stays 100mm in ODF and renders there), so
