Subject: [PATCH] Allow disabling `initialAwakenScrollBars` temporarily

To aid in migration of tests in preperation for enabling marking windows visible by default temporarily add a system property to allow disabling initial awaken of scroll bars. This property will be removed after test migration to allow default behavior.
