Scrollable Stage Text causes softkeyboard to "snap"

When using the new mobile Scrollable Stage Text input on iOS, I noticed that when the input gets focus, the keyboard does not do its usual ease in. It starts to slide in then about half way up, it just snaps to the top. This does not happen with StageTextInputSkin or TextInputSkin. I will attach a project that demonstrates the issue. Please note that this was tested using iOS 7 and AIR 4.0 on an iPhone 5S.

To replicate using the test project:
1) Tap on the first text input. It is using the ScrollingStageTextInputSkin and you will notice it does a strange snapping with the keyboard.
2) Tap anywhere on the screen to dismiss the keyboard.
3) Tap onto the second field (StageTextInputSkin) and notice the keyboard eases in normally.
4) Tap anywhere on the screen to dismiss the keyboard.
5) Tap onto the third field (TextInputSkin) and notice the keyboard eases in normally.

Another interesting test:
1) Tap on the first text input and you will notice it does a strange snapping with the keyboard.
2) Tap anywhere on the screen to dismiss the keyboard.
3) Tap on the first text input again and you will notice it behaves normally this time.
