Single tab in material design

[gkohen]

Hi,

I'm working on a tabs container that starts as a single tab and as you keep interacting with the application, you keep adding more. Problem is that when you have only one tab, the ink bar does not show up. Is that by design? I could not find reference to this case in the material guidance for when you'd use dynamic tabs. The code in Angular Material checks the following:

var hideInkBar = !selected || tabsCtrl.count() < 2 || mdNoBar;

Should this behavior be at least configurable?

Thanks
