No Electron LED when wake on pin

I guess this isn’t a real problem as everything works but it can be damn confusing.

On an Electron sitting on my desk running 0.8.0-rc.11 I triggered the ‘wake on pin’ to wake it from sleep. The serial monitor showed all the usual messages as it performed it’s normal sequence but the main multi-color Electron LED was totally off and never came on. I don’t do any control of the LED in my code. On every other occasion the LED has come on with ‘wake on pin’.

We just had a quirky situation in the field with a separate Electron where we thought our input wasn’t working but now I suspect there was no issue and it only appeared that way because the LED didn’t come on.

Has anyone else experienced this or is this actually expected behaviour?

Let me ping someone that might be able to help, @rickkas7, @ParticleD, or @mstanley are you able to assist?

Thanks. I should have taken a video as I imagine it sounds pretty implausible.
