Changing entities between Point and Billboard while their HeightReference is not equal to 'NONE' slightly alters the colour

Hello everyone.

We have noticed that in our application, once you switched the “style” of an entity (replacing Point with Billboard and viceversa), the colour would be slightly altered.

After some testing using Sandcastle, it appears that this only happens when the HeightReference property of the entities are not set to NONE. According to my colour picker, the colour value goes from rgb(211, 211, 211) to rgb(175, 175, 175).

The test we used in Sandcastle can be found here

Best regards and thank you in advance.
