Pop-up dictionary overflows top of viewport on review page

[cblanken]

If there are too many definitions in the popup dictionary for a term, the popup may overflow the top of the screen. Like this.

Thank you for the bug report!

I think it is only possible to fix by forcing the position to be under the words on the review page. I don't think I can check if it has enough space with the same method in the text reader, because of the way the review card works with its turn-over animation.
