Subject: [PATCH] Bug 1771344 - Add TextureClient::IsValid() check to
 PersistentBufferProviderShared::SetKnowsCompositor() r=gfx-reviewers,lsalzman

Device reset in test_device_reset.html replaces CompositorBridgeChild to a new one. And shutting down old CompositorBridgeChild also destroys TextureClients.
