Physical Switch stops working when in LockTaskMode

After calling StartLockTaskMode() the power switch on my device no longer responds.

Usually i get something along the lines of

18:31:56.462 488-488/? I/ActivityStackSupervisor: START u0 {act=android.intent.action.ACTION_REQUEST_SHUTDOWN flg=0x10000000 cmp=android/com.android.internal.app.ShutdownActivity (has extras)} from uid 1000 on display 0

08-16 19:04:43.825 488-488/? D/WiredAccessoryManager: --- max-chen dc_det disconnect 

from what i gather when the switch is toggled in WiredAccessoryManager an event is registered and that triggers a broadcast to shutdown. It appears like WiredAccessoryManager is being blocked when in LockTaskMode, i see nothing in my console when the power switch is toggled.

Any Suggestions ?
