Stopped millis() timer after Sleep

Hi
CubeCell after switching to sleep stop count timer millis()
example from default LowPower_WakeUpByTimer.ino

16:52:41.334 -> into lowpower mode, 5000 ms later wake up.
16:52:41.334 -> millis() = 46
16:52:41.334 -> millis() = 46
16:52:41.334 -> millis() = 46
16:52:41.334 -> millis() = 47
16:52:41.334 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:45.331 -> millis() = 47
16:52:46.345 -> wake up, 5000 ms later into lowpower mode.
16:52:46.345 -> millis() = 47
16:52:46.345 -> millis() = 47
16:52:46.345 -> millis() = 47
