If you access the demo from Videogular2 on Firefox, when the timer hits the CuePoint it shows the track with the "object" as the CuePoint info-layer on the side.
On Chrome it works just fine.
There is a way to keep the cue-points and hide the track? Maybe with CSS or something like that.
Thanks!
Probably is to late, but you can hide them adding this rule to the css
::cue { visibility:hidden;}
