v1.0.0-rc.3 popover seems broken


I’ve just updated to last v1.0.0-rc.3 and it’s seems that my popover are broken.
The backdrop is active but the popover itself doesn’t pop.

Works well on both my device and my computer (ionic serve --lab).

It’s cause i’m using angular bootstrap calendar the two css collide. I need to find a way to make them work or find another calendar without jquery.
