carousel breaks on dynamic slide add and scroll

[totano]

as seen in this plunker, if you add a slide and force scrolling right or left, rendering up.

You can see that also in the demo page (https://angular-ui.github.io/bootstrap/#/carousel),
move on last slide and then quickly click the Add Slide button and then the carousel next control arrow,
the UI will flicker and then the carousel will become unresponsive.

As a temporary fix I'm using $timeout after setting the active property

This appears to be a bug when on the last slide - is this correct?

[totano]

this happens when on the edge slide (both last and first) after adding a new slide and advancing the carousel, both manually (setting active to false on the current slide, and true on the following) or clicking carousel prev/next controls.
