sorry for the wait! looks great, just one small comment

[matthewgallo]

One thing that I caught was that when you open a "stack" with multiple coachmarks, clicking on the close icon closes all of the coachmarks currently open in the stack. In the previous implementation, it just closes the one that is visible. I think it's fine to re-visit this but we should match the previous behavior.

@matthewgallo That looks like a bug. I can open a separate issue for it if that’s okay?
