Short description of error
"Material Preview" shows always the material output assigned to eevee, but I want the cycles branch. Changing renderengine or the active material output node doesn't change anything.
Exact steps for others to reproduce the error
Open the blendfile and try to preview the material with "cycles" image - without going to rendered viewport. The material preview seems to always use the node tree going to the Eevee material output node, even when the render enging is set to Cycles.
