Huawei Nexus 6P :: Screen Wakes When Losing / Reconnecting To Data

I noticed that when my phone was sitting still the screen would randomly turn on, not just to the ambident display screen but to the lockscreen. I realized it was happening anytime the phone lost its data connection and had to reconnect. I can replicate it by turning airplane mode on then off and immediately turning the screen off with the power button. After about 5 seconds, the screen turns on again on its own. I've tried disabling ambient display, daydream, tasker, and bluetooth, but it still happens. I have unlocked the bootloader and changed the dpi but everything else is stock, no root.
