Issue while delete/cut-paste with enableSmartRendering true.

Scenario I:-

  1. Load 50 nodes. Each node has 50 children. (Total 2500 nodes)
  2. Select all the 50 children of first node
  3. Delete them

The nodes get deleted but there are whitespaces being shown in place of the deleted nodes.

Unfortunately the issue cannot be reproduced locally.
Could you provide with a complete demo, where the problem can be reconstructed locally.
