In fullscreen mode, the window property of cocoaView may not be the key window, and the current implementation would not grab mouse in fullscreen mode after left clicks on relative input devices.
This patch used isFullscreen value as a short-cirtuit condition for relative input device grabbing. Note that this patch should be tested after applying a previous patch which fixed event location conversion for relative input devices.
