Widgets under Retainer dont display tooltip widget.

I have a bunch of widgets under a retainer, these widgets dont display tooltip. Removing / replacing the retainer with others like overlay or canvas, the tooltip popped back up. Tried two projects with UE 4.15, both with the same result.

Is there any way to go around this? I use retainer box to optimize the blueprint tick time and now im lost because i cant show tooltips.
