Pull request overview
This PR adds a ReactFlow-specific “catch container” node type so that Catch nodes with nested content can render differently from leaf Catch nodes, and refactors test helpers to reuse a shared createFlatGraph utility.
Changes:
- Added detection of
Catchnodes that have child nodes and map them to a custom ReactFlow node type (catch-container). - Registered a new ReactFlow node type/component for catch containers.
- Extracted a shared
createFlatGraphhelper intotests/test-utilsand reused it across tests.

LGTM, I tried to improve getCatchContainerNodeIds() but please check if it does what expected as I only tried with pnpm test
