EA app 13.796: Battlelog launch of Steam BF3 times out

EA app 13.796.0.6309, BF3 Steam version (app 1238820, offer DR:224766400). Battlelog server joins (requestSource EALocalHostSvc) enter proxiedLaunchGame without redirecting to Steam, so no EASteamLauncher is running to receive LaunchGameInfo; launch times out with ProxiedLaunchTimedOut, processId 0. A launcher started via steam://run during the wait sits in WaitingForLaunchGameInfo and shuts down on the timeout. Client-initiated launches do redirect via steam://run/1238820//. Previous client 13.686 Link2EA asserted on the new steam2ea:// URL at update time.
