Hello,
Apologies if this issue has been posted about already, I couldn't find it.
My university is using H5P as a plugin, we have Moodle as our Learning Management System. I create all H5P content in the content bank. When I create H5P content and I edit the activity, the textbox collapses and I'm no longer able to edit my work. I have to save the H5P content and return to the edit setting. It's very annoying, as it happens every few minutes. I have this issue with several H5P content types. My cache and cookies are cleared. I also have this issue in several browsers.
Others have this issue too, https://h5p.org/node/1298973, and it seems to be a Moodle bug.
Any idea what can be done?
