Tons of DH chunks lost in shadow when render distance greater than shadow distance

What happened?

When setting render distance from 7 to 8 chunks, about 95% DH chunks disappeared in shadowmapping, when world time is set to 23500 (not sure if this also exist on other time) and shadowDistance is 120, even most of them are not expected to disappear

Screenshots

Render distance set to 7, about 440 DH chunks are rendered in shadowmapping

After further testing, this seems to happen when render distance >= shadow distance, for example, when shadow distance is set to 240, if render distance is greater or equal than 15 (15 * 16 = 240), then this will happen
