Automatic scroll when TextView edit begins

[modularthoughts]

I just noticed that when the chat view is at the bottom and I tap the input view, the chat view doesn't scroll up, and the last bubbles of chat get hidden by the keyboard view. When I tap outside the keyboard, the keyboard get dismissed but the chat scrolls back down with it, as if it had been scrolled up before and now "wants to get back" to its initial position. Though, when the chat view is not at the bottom, if I tap the input view, the chat does scroll up in a normal way, and when I tap outside the keyboard it scrolls back to its initial position. How can I fix the scroll behavior when the chat view is at the very bottom? Thank you.
