Procedural Skybox Sun changes size switching between Simple/HighQ

How we can reproduce it using the example you attached:
a. In Test scene select New Material
b. Switch 'Sun' between Simple and High Quality
---> Sun size changes quite heavily. Looks like the scale of change depends on the Sun Size param - for some value the change will be almost innoticeable. For some - it is more than obvious.
Expected: Size of the sun should stay about the same.
