TextInput contained in Scroller causes problems

Problem 1:
The text (eg. "hello world") of TextInput hangs when a parent Scroller is dragged.

Problem 2:
TextInput is not inside the ViewPort of the Scroller. TextInput text is not clipped.

Note:
The exact same problem exists for TextArea
A list is basically a Scroller - TextInput in lists/itemrenderers therefore also have problems.

Problem 1, Case:
TextInput text is "hello world"
TextInput is displayed in a Scroller which can scroll (ie too much information on the screen)
I drag my finger over the screen to scroll the Scroller.
The text "hello world" stays put while everything else scrolls as expected
I release the display
"hello world" is now drawn in the TextInput again
If there the scroller slides the view slowly after releasing the finger, "hello world" correctly follows the view.

Workarround:
skinClass="spark.mobile.skins.TextInputSkin"

Conclusion:
The problems are caused by StageTextInputSkin
