Disabling auto sizing in Moodle

Is there a way to disable/override the H5P activity auto resizing? Some of the activities appear way to big for the screen ( as they are displaying at 100% width) and are therefore unusable.

I've tried removing the dynamic sizing script in the HTML code and adjusting the width/height, but this doesn't work. Moodle just automatically puts the sizing back to 100% width!
