Thanks for the detailed analysis Alexandros. I am able to reproduce the
issue reliably on my arale, looking into it.

Note that the fact that keepDisplayOn is requested twice is expected:
chromium instantiates one PowerSaveBlocker per stream, so for a video
with audio, that’s two streams, hence two requests. Perhaps not the most
efficient thing to do, but it should be okay as long as the
corresponding removeDisplayOnRequest requests are emitted where
relevant.

Bug description:
  rc-proposed, r140, krillin

  There are times when it seems the display blanking policy stops
  working and the display stays on until I press the power button.

  Steps to reproduce:
  * install and start Siete
  * put it in background

  Expected outcome:
  * the display is switched off after a predetermined amount of time

  Actual outcome:
  * the display stays on forever

  ======

  Now that apps can request the screen to stay on, they can do so
  regardless of whether they're focused/visible or not.
