A "tall" birch tree generated in a meadow biome with a bee nest. A campfire was placed directly below the bee nest at ground level (the same y-level as the lowest birch log). Honeycomb was harvested from the bee nest with shears, and the bees were aggravated despite the campfire below the nest.

What I expected to happen was...:
A campfire placed as such (at the same y-level of the lowest log on a naturally-generated tree) below a naturally-generated bee nest should allow for harvesting of the nest without aggravating the bees.

What actually happened was...:
Bees were aggravated despite the presence of the campfire below.

Steps to Reproduce:
1. Generate a "tall" birch tree with bee nest.  The screenshot shows a bee nest generated in the following seed (1370342242177215943) at the following location (238, 119, 171).

2. Place a campfire directly below the bee nest at the same y-level at the lowest log of the tree. In the example in the screenshot, the campfire was placed at (238, 113, 171); an azure bluet that generated there was broken in order to do so.

3. When possible, use shears on bee nest to harvest honeycomb.

4. Observe the reaction of the bees (bees will attack player and subtitles will say "bee buzzes angrily").
