### To Reproduce
<!--
Your best chance of getting this bug looked at quickly is to provide an example.
-->
updated electron quick start app:
[no-native-window-buttons.zip](https://github.com/electron/electron/files/5209788/no-native-window-buttons.zip)

this will start app in fullscreen mode. Do Bug button just set fullscreen true and false consequentially.
