Content disappears caused by Readspeaker

Hi,

we are using the latest (v 1.15.0) of the H5P Plugin and the Readspeaker from https://www.readspeaker.com/.

When somebody starts the readspeaker, all the contents of the H5P iFrames disappear. There are no errors in the console.

You can find an example here: https://www.mebis.bayern.de/infoportal/lernplattform/einschreibemethoden/

Is there a possibility to reinitialize the iFrames? What else could i do?

Thank you in adanve for your support. 

Best regards.
