Page shouldn't scroll when select is clicked and options are shown. See main example.

What is the current behavior?

Page scrolls. Scrolling is not disabled.

What are the steps to reproduce?

Using materials v2.0.0-beta.3, add this code into the template of a component:

<md-select [(ngModel)]="address.state" name="State" placeholder="State">
            <md-option *ngFor="let state of states" [value]="state">{{ state }}</md-option>
</md-select>

then open the select box, and scroll on the page.

Better user experience.
