• iOS Runtime: 5.1.1

Describe the bug
iOS TextView content shifts up and gets partially clipped on every other newline character input

To Reproduce

1. Input some text
2. Input newline -- textview resizes properly but content shifts up and gets partially clipped
3. Input newline -- textview resizes properly and content offset is OK -- content visible

Expected behavior
Textview should not exhibit alternating behavior on inputing newline -- content should always be visible

Sample project

Additional context
The cause of the problem is described here:

The problem is that UITextView's scroll animation and your frame setting action were happened at the same time. UITextView internally scrolls the texts you currently typing to visible when typed one more character at the end of the line or typed the new line character. But the scroll animation does not need because you are expanding the textview. Unfortunately we can't control textview's internal scroll action so the text scrolls to the top of the expanded textview weirdly. And that weird scroll makes unnecessary bottom padding too.
