Doesn't stop audio on click in Firefox?

Question

AJAX

Tell me who can come across? There is a test component on the site. You can embed an audio question. ajax component. In chrome, everything works fine, when you go to the next question, the audio from the previous question stops and the audio starts from the next question.
In Mozilla, the audio from the previous one does not parry, as a result, 2 audios start playing and overlap each other. What could be wrong with Mozilla?
