The Egl backend opens the drm device and creates a gbm_device from it. From that it creates the EGL device. The EGL device outlives the EGL backend (e.g. for compositor restart). So far the EGL backend destroyed the gbm_device when going down which mesa did not like at all when a new context got created on that EGL device. Thus the ownership of gbm_device is also passed to the Platform so that the compositor can be restarted. This makes the TestSceneOpenGL no longer crash during the restart compositor test.
