If you click on the arrow in the upper right corner of an album on your profile page, you see a menu with an ashtray menu item.
It's supposed to be a trashcan, but maybe it looks like an ashtray...
I you click on that menu item, the album is not deleted as expected, the display is dimmed and no more interaction is possible.
If you scroll down you'll see a popup asking you if you are sure you want to delete it. This popup is placed in the middle of the screen, and iOS unfortunately report the page height instead of the screen height. I'll see if there is a better way of placing it.
