Translucent geometry not rendering as well as it used to?

[mramato]

Somewhere between 1.50 and 1.51 translucent geometry started rendering differently

1.50
https://cesiumjs.org/releases/1.50/Apps/Sandcastle/?src=CZML%20Custom%20Properties.html

1.51 and 1.52
https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=CZML%20Custom%20Properties.html&label=All

@hpinkos @bagnell @lilleyse any ideas here? I haven't bisected yet...

This might be specific to this example. For example: http://localhost:8080/Apps/Sandcastle/index.html?src=CZML%20Rectangle.html&label=All seems to work (look at PA)

@wangxiaolun can you post what you're seeing? It looks correct to me:

Note that we recently made some changes that might make it look slightly different than before, but you can still see the changes in lighting for the different faces of the geometry.
