The bug
If a spawner is set to spawn lightning bolts, a full lightning bolt is displayed, unlike miniature models of entities as usual in a spawner. Previously, lightning bolts were not rendered and could not be spawned using a spawner, but that has since changed, and now a full lightning bolt is rendered, spinning around the spawner.
When a player leaves the area around the spawner, the lightning bolt freezes in place. While looking from certain angles (upwards) at this frozen lightning bolt, it can become invisible.
The expected behavior is that either:
The lightning will not render at all and will not be spawnable by spawners, or
The spawner will render miniature model of a lightning bolt instead of a full-sized one
How to reproduce

Can confirm this in 21w39a. The expected behavior would be that lightning bolt spawners would not render the full lightning bolt. Instead, it should only render part of it, or have it render really small to fit inside of the spawner. Please also take into consideration that the command usage of spawners has changed in 21w37a. You can use the following command to reproduce this in versions 21w37a and above.
/setblock ~ ~ ~ minecraft:spawner{SpawnData:{entity:{id:"minecraft:lightning_bolt"}}}
