Audio bar not responsive

Hello! It has caught my attention that the audio bar iframed from h5p doesn't seem to be responsive. It seems to have a set length, unchangeable by us through the iframe. I have seen that you have a resizer, and we use this for other elements, but the audio bar in specific isnt responsive within the iframe itself, so I doubt this would help in this instance?

Example: 

Normal

Smaller size

Expected

Have you tried ticking the "Fit to wrapper" option? If yes, could you please be more specific about your setup as it feels crucial to know about in order to answer your question.
