Horizontal Filmstrip broken

Horizontal filmstrip (#interfaceConfig.VERTICAL_FILMSTRIP=false) appears to be broken.

Only shows grey screen and the following errors in console:

Reproducible in alpha and beta as well.

Not sure if anyone actually uses that feature or if it is on the way out, but thought I should raise this just in case this was unintended and not yet on anyone’s radar.
