Bug, feature request, or proposal:

For <md-select/>, tabindex attribute value is set to 0.

What is the expected behavior?

tabindex should have the given value.

What is the current behavior?

It is rendering tabindex="0" when using <md-select tabindex="6"></md-select>

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

• Angular 2.4.9
• Material 2.0.0-beta.2

Is there anything else we should know?

Issue in the following lines:

export class MdSelect implements AfterContentInit, ControlValueAccessor, OnDestroy {
  /** Returns the correct tabindex for the select depending on disabled state. */
  _getTabIndex() {
    return this.disabled ? '-1' : '0';
  }
}
