Positioning error

[francisjervis]

Hi, sorry for the delay (I stopped receiving notifications for some reason). Since you closed the first issue, posting a new one with the code that got me that position behavior:

Backdrop is working now, too.

Now the backdrop is working, the parent seems to have changed from the main view (ie. excl. nav bar) to the full screen.

Can obviously work around by changing the point y values for now. Thanks for all your help!!
