Mind Map in full screen view

Thomas Picketty, Mind Map:

when viewing full screen and on the lower level graphics clicking the file/attachment icon, a text box opens, however, i would like to highlight 2 issues
1. this does not close when tapping elsewhere on the screen (user has to tap the file icon to close the text box)
2. this is displayed beyond the screen margin if the graphic's file icon is too close to the margin (only by chance did I realise this text box can be moved on the screen by tapping, holding and moving)

On this same full screen view, the bottom banner "2015 Macat…" is not displayed in full height

iPhone5, iOS 8.1.2
Safari

Please see screenshot. I hope this is helpful, regards
Simone
