Show back button when access from different tab

My app has two tabs, home and about, with the structure below

  1. Tabs -> Home
  2. Tabs -> About -> NavStack

If I access NavStack from About tab, back button shows in the header, which brings the page back to its parent About tab. But there is no back button if I access from Home tab (linked by ui-sref).

How can I make the back button shows even if I access it from Home tab and it should links back to About tab when clicked.

I have created a codepen here.

Try this thread Ionic tabs "auto" navigation
But generally, it is a lot of hacking and I would recommend to choose different navigation strategy - for example I open all pages in the current tab as Facebook does it.
