Enable resource sharing for D3D11 devices created with WARP ANGLE currently blocks resources sharing if ANGLE was initialized using EGL_PLATFORM_ANGLE_DEVICE_TYPE_WARP_ANGLE. This is to prevent applications from trying to share resources between hardware D3D devices and WARP. However, this prevents developers from deliberately initializing ANGLE to run on WARP, and then sharing resources with an external WARP device. ANGLE should support that scenario.
