After pausing, playback does not start properly

[christophberger]

Hi,

Thanks for having created this great extension!

While testing the features, I stumbled upon a usability issue. In short, when playback is paused, then calling typewriter.playback only prints the first letter of the text and then stops until calling typewriter.pause again to resume.

I would have expected that calling playback after pausing automatically clears the "paused" status.

Thanks
