Embedded iframe - fullscreen button throws a JS error

Hi!

We've encountered a problem with the external embedded Ziggeo player that I think wasn't there before. We display previously recorded videos with the ziggeo.io/p/<video token>, and at some point the fullscreen button started throwing the following:

This only happens for the external embeddings - the ones embedded via Javasript still work.

(Not sure if this is important, but when I look inside the iframe, it references v2-r32 for the Ziggeo proper, but v2-stable for player-adapter.js, which is r33...)

Thanks you in advance!
