This is a very useless thing to fix I would say and should not be considered, but it still is a bug in my opinion.

When you fall on a block, usually there are impact particles if you fell from a high enough height, but this also happens with light blocks and structure voids.

If you (for short) impact on the center of a block, usually the block's texture would be used as particles, and even if you land on the side of Block A for example, it can be Block B's texture being used, and the part of this that relates to the main summary is that if there is a light block or structure void there, the particles will be shown are those.

The videos uploaded show both of their particles in action and images of those particles for easier viewing.

Extra Information:

I'm pretty sure this happens for every version since this block was added (1.13)
