Hi, all

I check the code in desktop_factory_ozone.cc. The views::DesktopFactoryOzone::GetInstance() should be used after SetInstance.
But I can't find any place where call the DesktopFactoryOzone::SetInstance().
I think there is a bug on it.
Is it fixed now?

BestWishes!

Hi.

I believe this code has even been removed from Chromium Tip of Trunk. See https://codereview.chromium.org/2830933006/.

I tried to answer a similar question about Content module and Mus here: https://groups.google.com/a/chromium.org/d/msg/ozone-dev/Wd9b7REsBR8/kAkYfhyxAQAJ
