Block Model Elements Rotate only on 1 Axis

I was messing with one of the elements in the JSON file for the upper sunflower block model to create some variety, and I wanted to rotated it on 2 axles instead of 1, but it only gave me a rotation on one axle or the other.

What I expected to happen was...
The element would be rotated 2 ways

What actually happened...
The element only rotated 1 way

Steps to reproduce
1. Open the JSON file "double_sunflower_top"
2. Identify the element for the actual yellow flower
3. Identify the rotation of the element
4. Copy and paste the rotation under the element (so there are 2 rotations)
5. Change the "axis" of one of the rotations to y
6. Change the "angle" of that same rotation to 45
7. Save, open a new Minecraft world, place some sunflowers

Below is an example of the problem. The sunflower on the left should have 2 rotations instead of the 1.
