Bug listening with space key

Playing a listening round, I get an error like when the network connection is interrupted. This is on desktop, so I don’t think any such thing happened. After that, space triggers sentence audio, so I can’t type space in the text area any longer, I have to copy paste it from somewhere else to go on. The control key works normally. Also, whenI press space, the audio plays, but I also get a dialog that says:

Oh no! There was an error with the audio
undefined undefined
Sorry about that. Please try again etc etc.

If I close the round things get back to normal. This is on mac, firefox 135.0.1 if it matters. Thanks.

It happened again but instead of ‘undefined undefined’ it was ‘[object event] undefined’ :-/
