Dev tools prevent sleep

When dev tools are opened in the last couple of Chrome releases, the screen won't turn off and there is no sleep for my Windows 10 laptop.

```
powercfg /requests

DISPLAY:
[PROCESS] \Device\HarddiskVolume6\Program Files\Google\Chrome\Application\chrome.exe
Capturing

SYSTEM:
None.

AWAYMODE:
None.

EXECUTION:
