This was fixed today. It was apparently an igv.js bug: https://github.com/igvteam/igv.js/commit/87fd454f4e7cd9ca949d78ef9dacb8bb72da00dc
Still not tested, waiting for feedback in here: https://github.com/igvteam/igv.js/issues/1077#event-3164924058

or
https://igv.org/web/snapshot/dist/igv.esm.js
if you use modules.
Sure, I'll test and let you know!
