Regression - RTE #1009 when using Flex SDK 4.5.18623

Hi all,

I receive the following RTE

Error #1009: Cannot access a property or method of a null object reference.

a tflashx.textLayout.edit::EditManager/handleUpdate()

at flashx.textLayout.edit::EditManager/finalizeDo()

at flashx.textLayout.edit::EditManager/doOperation()

at flashx.textLayout.edit::EditManager/flushPendingOperations()

at flashx.textLayout.edit::SelectionManager/enterFrameHandler()

when starting to typing a text into Spark TextInput control from the sample code placed below.

Please notice, that I am adding event listener for TextEvent.TEXT_INPUT event in capture phase
