The Bug

Bees spin when right on top of scaffolding. This usually happens when the bee cannot go anywhere and can only stay on top of the scaffolding.

See the video attached for a more detailed view.

How to Reproduce

See the image attached.

1. Make a scaffolding pillar however tall you like, and surround it with glass.
2. Extend the glass pillars by two more blocks and then cover the top.
3. Spawn a bee inside of the scaffolding.
4. Note how when the bee rises and lands on the scaffolding, it will spin.
