Yah, I'm not sure what we want to happen here but this may actually be desired. Tom, Sebastien: thoughts?

Playing with Android, it appears that scrollbars appear & fade out whenever the app is first focused. It seems reasonable for us to do the same thing.

+sgabriel -- thoughts?

I did not see scrollbars appears & fade out whenever the app is first focused on Android Chrome but I see it on Gmail.

Do we need same behaviors for tab change(Aura/Android)? 

Is is a common pattern throughout Android or just something that happens for gmail? 

sgabriel@ I seen this pattern on many Android APPs not only gmail.

Interesting. Happy to try that on window focus, not sure if we want to replicate that for all tab switch within Chrome. Seems a bit heavy-handed.

Ok, let's start with just window switches and see how it feels. It's actually pretty subtle on Android, so I could see it working okay for tab switches too.

For now, this flash is caused by a bug https://bugs.chromium.org/p/chromium/issues/detail?id=696717 .

I will fix that and implement this one later.

It seems that scrollbars no longer flash when switching windows (59.0.3041.0)

tbuckley@ This is a bug for handling mouse up event incorrectly. I filed in https://bugs.chromium.org/p/chromium/issues/detail?id=696717. Show overlay scrollbars when switching windows is not implement yet.
