Hi there! When you click on your font-list, and try to scroll, it closes the selection-dialog-panel, as if you pressed "close". I've created a small video where you can see the problem and where it occurs.
I tried to do some CSS stuff regarding the z-index etc. but the problem looks unsolvable on this level.

This didn't happen on previous version of iOS. I get a lot of complaints from customers so hopefully this can be fixed.
