wavesurfer.js: Error raised when trying to seekTo on Firefox

Hello, When I try to click on any part of the waveform on firefox, this error is raised :

TypeError: Value being assigned to HTMLMediaElement.currentTime is not a finite floating-point value.

Looking at the sources, it seems that in this function :

this.drawer.on("click", function(e, progress) { setTimeout(function() { console.log(progress); my.seekTo(progress); }, 0); });

the value of progress is Infinity

At this point, I don’t know what to do to solve this, any ideas ?
