Frequent AttributeError for 'isBelowLockScreen' on Certain Screen Lock

[AAClause]

Sometimes, on the lock screen (Windows+L or automatic locks), NVDA regularly floods the log with the following error:

ERROR - utils.security.objectBelowLockScreenAndWindowsIsLocked (20:27:31.056) - MainThread (3416):
Traceback (most recent call last):
  File "utils\security.pyc", line 173, in objectBelowLockScreenAndWindowsIsLocked
AttributeError: 'Dynamic_WebAccessBmdtiGecko_ia2' object has no attribute 'isBelowLockScreen'

Sadly, I can't reliably reproduce it.
