Bugs in content types

Hi there,

Title says it all. I am attaching 2 screenshots taken from this site's demo page at: https://h5p.org/memory-game that show the problem. Display is OK in Chrome and MS Edge browsers, but not as expected in FF.

BTW, in FireFox the text "A free HTML5-based memory game content type allowing authors etc." at the top of the memory cards is not even displayed. Most strange!

PS It is not clear if bug reports should be created in the H5P forums or attached as comments to an H5P activity.

Firefox freezes when using the newest library "official-h5p-release-20161206_0"

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue."

1. Install lates 1.22 Drupal h5p module
2. Install all libraries "official-h5p-release-20161206_0"
3. Create question set with multiple choise questions
4. test with firefox on windows 10

After uninstall and using this library "official-h5p-release-20161020"  problem disappeared

I've identified two possible options for fixing this:
