In particular CaptureSynchronizer assumes a single CaptureClient, but that isn't true when using DesktopNativeWidgetAura. Either DesktopNativeWidgetAura needs to have the option of a single CaptureClient, or CaptureSynchronizer needs to change to support n-CaptureClients.
A bunch of interactive ui tests (in views) fail because of this.
