Bug: Animation of tooltips not working in combination with ChangeDetectionStrategy.OnPush

What is the expected behavior?

The animation of mdTooltip should work with ChangeDetectionStrategy.OnPush

What is the current behavior?

First there is just a small rectangle with the background color of the tooltip visible. Then it directly shows the full tooltip. Also if I slightly move the cursor above the md-icon-button, the tooltip "jumps" between not visible, fully visibly and just the small rectangle.

Which versions of Angular, Material, OS, browsers are affected?

Angular 4.0.2
Material 2.0.0-beta.3

Is there anything else we should know?

It worked with 2.0.0-beta.2
