Since 4-addr frames completely override the source address which will make it into the converted 802.3 frames, receiving frames for other 4-addr stations will confuse the bridging code. To be able to handle traffic for all connected devices, the bridge code will automatically turn on promiscuous mode, which triggers this problem.
