[Bf-committers] Fix T45317: Cycles material preview unnecessarily re-rendering

[Sergey Sharybin]

Hi,

I don't think you can trigger refresh of material from the custom node and
in fact this sounds like an API regression which better to be resolved from
our side.

Do have a patch for this [1] but before going ahead want to have feedback
from our python/rna department.
