ID 359709 - Katana runs concurrent renders upstream of ImageMerge node

Problem summary:

Kicking off a Preview Render from an ImageMerge node should not kick off two renders from different branches simultaneously, however it seems that it is possible to get Katana to do just that.

Steps to reproduce:

  1. Download and open the simultaneousrender.katana project file attached to this ticket.
  2. Set the View and Edit flags on the ImageMerge node.
  3. Right-click on this node and then choose Preview Render.

Expected behaviour:

Katana should not start two image renders simultaneously upstream of the ImageMerge node.

Actual behaviour:

Katana kicks off two image renders simultaneously, with the following shown in the Render Log:
