Found it! It was missing support for XTerm control sequence REP (https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h4-Functions-using-CSI-_-ordered-by-the-final-character-lparen-s-rparen:CSI-Ps-b.1CA2).

The patch is in develop now, will be released soon with v3.0.0-beta.3.

New player with the fix has been pushed npmjs.org, and asciinema.org was updated to use it already.
