説明

Environment

  • Package version(s): The latest @blueprintjs/core@4.20.1, @blueprintjs/popover2@1.14.9
  • Operating System: macOS
  • Browser name and version: Edge/Chrome

Code Sandbox

Actual behavior

If the tree node has many children nodes, and these children nodes are wrapped with ContextMenu2, when expanding the tree node, it's stuck for seconds to expand its children. If the ContextMenu2 is removed, the expanding is very smooth.

The sandbox uses the treeExample from the blueprint itself and makes a little change to demonstrate this problem.
