* Reworks the tooltip to reuse the `OverlayRef` after the first time it is opened, rather than destroying it and creating a new one for every subsequent open. This reduces the overhead from having the create the new overlays all the time. * Changes the signature of the `ConnectedPositionStrategy.withScrollableContainers` method to return the position strategy. This is primarily for consistency with the other methods.
