[iOS] Scrolled breadcrumbs on app launch

When launching the iOS app, we resume focus on the node that was previously focused when the app was last used.

However, the breadcrumbs don't scroll to the leaf node that is focused, so you end up in a state where the focused node may not be showing in the breadcrumbs bar.

Thanks for the report. The breadcrumb bar doesn't scroll to the focused node, so on launch a deep path leaves it off screen on the right. I'll fix it so the bar scrolls to keep the focused node in view.

Fixed in 1.15.3. The breadcrumb bar now scrolls to keep the focused node in view. https://forum.kosshi.app/t/23
