Issue Detail
The back button visibility was not updating correctly when the page did not have a NavigationPage.
Root Cause
The back button visibility was being updated only when the parent was a NavigationPage. As a result, it did not update properly when there was no NavigationPage.
Description of Change
Only the toolbar visibility was updated when the page did not have a NavigationPage. Now, the back button visibility is also updated along with the toolbar visibility to resolve the issue.
