alignVertical = bottom causes auto undefined error

On a common controls label, setting alignVertical to bottom causes this code generation (and error and error about auto undefined):

  NSB.addProperties(MenuLogoutContainer);
  NSB.bs.addProperties(MenuLogoutImage, 'Image_bs4');

  MenuLogoutLabel.style.lineHeight=auto*2-16-2;
  NSB.addProperties(MenuLogoutLabel);
  NSB.addProperties.addChild(LoginContainer);

It’s using the height property in the calculation, which defaults to auto.

We’ll fix this.
