I just tested in 1.12. Pushing a primed TNT entity north and/or west with water visually shows the TNT going through solid blocks in the same y coordinate. The primed TNT entity will also visually snap back to its actual position. Using a repeating teleport command, the player is not teleported to the entity as it phases through blocks, so it's just a visual glitch. The TNT entity does not phase through the blocks immediately, but instead waits a random interval of time of about 2-3 seconds. The TNT entity cannot change y coordinates it appears. The fuse timer is unaffected by this glitch too.

I believe this is not a duplicate of the before mentioned bug, as the bug MC53915 describes TNT as clipping through a block while this bug instead s observes the TNT visually appearing to clip through a block, while it actually remains in place.
Please correct me if I'm wrong.
