Bugs in content types

In the Dialog Cards activity, it seems that the feature to scale longish texts so that they fit inside the cards does not work consistently when the longish text resides in the Answer (back of the card) and the Text (Front of the card) has a short text.

Please look at my example here: https://h5p.org/node/56734

1. Drag text box to edge of slide and centre. Save and view.  Text no longer centered
2. Desktop
3. Browser: Chrome
4. H5P web
5. Course presentation

Hi, I put a H5P quiz (Question Set) at the bottom of my page. I can scroll up and down my page, but as soon as I start doing the quiz, the page gets stuck and I am no longer able to scroll back up the page.  

Is there some way to fix this?

Thanks in advance!
