Issue with h5p-resizer.js in FireFox when upgrading from Moodle plugin Ver. 1.20.2 to Ver. 1.21.
We have a local moodle server setup to host our H5P content. We embed our H5P content in our Brightspace LMS and use the h5p-resizer.js to handle responsiveness. It was operating perfectly until we recently updated from Moodle plugin version 1.20.2 to 1.21.0. The update seems to have broken the h5p-resizer script. It only happens in Firefox, though. Which is odd.
We have a deveopment server that we reverted back to the older version of the plugin (1.20.2) for testing and the resizing script started working again. If we re-upgrade back to 1.21.0, it breaks.
See attached image to see a visual of what's happening.
Both chrome and firefox are updated to the latest version.
Our current moodle version is 3.9.1+ (Build: 20200717).
Any help would be greatly appreciated.
