Android 8 softkeyboardbehavior stretches stage

Testing on a Nexus 6P running Android 8 against the release version of AIR 30. When the keyboard appears, the application gets stretched upwards. Seems like the bottom of the stage is pinned, so when the top of the stage moves to new position the movie height increases, and all child objects scaleY is greater than 1.

Seems to be a problem with Android, since I can replicate the same issue in every AIR SDK back to 22.

Cannot replicate this issue on same hardware running earlier Android versions.

Is this a known issue? Haven't found any discussion about it here or elsewhere.

btw I have to use renderMode = direct because this is a starling app.
