During the development of a Matter over Thread product, I encountered the following issue:
After adding two Matter over Thread devices (an OnOff Switch and an OnOff Light) through a Matter border router and binding the switch to the light, the switch can directly control the light's on/off state. However, when the border router is powered off, the switch retains control over the light for about the first minute but loses this capability thereafter. The project is based on modifications to the light_bulb reference implementation. The version of SDK is 3.0.1. What causes this behavior, and how can it be resolved?
