Active vtkMultiVolume issues closed

Dear maintainers,

Recently, two issues were closed that were not actually solved for several years. I indicated this in comments but there was no reaction.

I’d like to ask if this part of the code is foreseen to be maintained, or the plan is to abandon it? I think in either case the solution should be different than simply closing the issues about existing problems. Thank you!
