It's important that we are able to present view controllers directly from the content view controller of the popover controller (see #25 for an example).
However, when we do, we get the following warning in the console:
Presenting view controllers on detached view controllers is discouraged
It's only a harmless warning for now, but it could become worse in a future OS update, so it really should be fixed.
I believe the fix should be to be able to pass a parent view controller through the API, and set the content view controller as a child of its parent, using the addChildViewController method (see documentation).
