Mineshafts can generate with light but without any torches

So... Been playing minecraft snapshot 21w07a, just exploring a grimstone cave when i found a mineshaft with lights.
Was searching for the source of the light there was nothing, no torches.
I left the world then rejoind the light was gone.

It's a weird glitch and it might affect in the experience, that's why i'm sharing it.

I Tried To Attach Screenshots But It Doesn't Work.

I was able to reproduce this in both 1.16.5 and 21w08b. It appears to be a client-server desync of the lighting. I suspect that the client thinks a torch generated in that position and the server knows that the torch did not generate there. This bug is relatively common.
