Having trouble with nav-bar attribute "leaving" and "entering"

Continuing the discussion from Please help test: Angular 1.3, improved transitions, cached views, etc:

@adam i’m experience this issue with Ionic v1.1.1 but not on nav-view attribute but on nav-bar attribute into ion-header-bar. The “previous” nav-bar does not became “cached” but remain “leaving” and “entering” nav-bar does not became “active”.
Thanks a lot.
