Back button is considered to calculate title left style even if it's hidden

If you add a custom button to left and set back button to be hidden using hide-back-button=“true” in ion-view, function self.calcWidths is considering the hidden back button on calculation of title left style making it to be centered and not respecting any configuration to force it to be left like using:
align-title = 'left’
or
$ionicConfigProvider.navBar.alignTitle(‘left’);
