working LGV in drupal test site but not staging.wormbase.org

LGVembed.js

//this exact JS works just fine at http://scottca.in/node/3
// but at https://staging.wormbase.org/species/c_elegans/gene/WBGene00001340#09f6--10
// the exact same JS (with an extra fetch to get the releaseVersion) nearly entirely
// works but does NOT offset the track labels--that is the only difference.
//
// Weird
