Expand this with something like
// We use an extra wrapper element in order to use make the overlay itself a flex item.
// This makes centering the overlay easy without running into the subpixel rendering
// problems tied to using `transform`.| private _rightOffset: string = ''; | ||

Add description for _wrapper that explains what it's for and that it's lazily created.

Let's make this required and give ConnectedPositionStrategy a no-op dispose, then we won't have to check whether it exists before calling it.
…ionStrategy Refactors the `GlobalPositionStrategy` to use flexbox for positioning. This avoids the subpixel rendering issues that come with using transforms for centering. Fixes angular#932.
