Ion-tabs vs either ion-header-bar or ion-footer-bar


#1

I’m using ionic-v1.0.0-beta.13 These cases display as I expect, since they target opposite page positions:
ion-tabs class=“tabs” together with ion-header-bar; or
ion-tabs class=“tabs-top” together with ion-footer-bar.

But these other cases don’t display as I expect, probably since they target similar page positions:
ion-tabs class=“tabs” together with ion-footer-bar,
which results in the footer appearing atop and so obscuring the tab bar; or
ion-tabs class=“tabs-top” together with ion-header-bar,
which results in the header appearing atop and so obscuring the tab bar.
In these last two cases, inspecting in a browser shows the tab bar and its individual tabs positioned in the UI, when moused over in HTML or DOM, highlighted beneath the obscuring header or footer.

I couldn’t find in the Ionic documentation that this mutual exclusion is intended. Is it? Is there some class or other fix-up to allow these features to be used together? I’m not necessarily arguing for this usage, but instead just need to know what to expect. Thanks.
