Bugs in content types

While testing BranchingScenario to see if the max score can be different for different branches I have found the case where raw score is greater than max score. This is out of the xAPI specs. 
Please see attached H5P file.
In my feeling it deals with the setting different score for end scren and changing the static to dynamic score. 

Steps to reproduce issue: 

I am running a site with Moodle version 3.8 and I have the latest version of H5P installed.  In Moodle when pulling a video from Youtube the playback rate doesn't work, that is, you can't change it from the default of 1.  Now, I think this is more of a Moodle issue than H5P because in Canvas the H5P Playback Rate adjustment does work with Youtube videos.  So does anyone know if I can get the Playback rate to work when running H5P from Moodle.  I have also posted this on a Moodle forum.  Thanks.

Hi,

I am new to H5P and need help with creating a timeline and essay with feedback assets. However, I don't have access to create these assets. Your inputs will be helpful.
