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.

Can confirm in 21w11a. This can be seen quite often.
