Cesium3DTileStyle - alpha value not respected for loaded tiles

See Cesium3DTileStyle - alpha value not respected for loaded tiles · Issue #11300 · CesiumGS/cesium · GitHub

When changing the alpha value of a Cesium3DTileset, already loaded tiles use the old alpha value and newly loaded tiles use the new alpha value.

Has anyone else faced this issue / has a fix?
