So let's take this simple script.

Now if we were to move it into the “blocks section”, it starts to disappear.

If we were to move it into the sprites area, it completely disappears.

If we were to release it in the sprites area, the script is not deleted. Instead it is taken back to its position before we moved it. Along with this, the comment is also gone.

However if we were to drag the script the comment appears again.

The same thing happens in the offline editor. (version 458.0.1)
Why is this happening?
