TNT Duper Bug

[DrSushi]

Describe the bug

When using a TNT duper, in my case the one from this video, while also playing on a Lan server (don't know if it works elsewhere) every TNT explosion causes every players torches to flash.

Steps to reproduce

1. Create TNT duper and turn it on
2. Get a headache from the flashing lights lol

Expected behavior

No response

Additional context

Thank you for the bug report! Unfortunately, this is intended, as the vanilla light block blocks explosion damage (see MC-221585). To ensure that no damage is absorbed, I turn off the entire system for a few ticks when a TNT is about to explode.
However, I've recently had a few additional problems with TNT entity light emission (#90, for example), so I might just remove it from the list of light emitting entities. Then I could probably remove this measure as well
