Pull request overview
Fixes a hierarchical grid cell-merging regression where child-grid cells remain unmerged after activation/selection moves to another grid (parent/sibling), by ensuring a merge-refresh trigger occurs when activation is cleared.
Changes:
- Emit
activeNodeChangewhen hierarchical navigation clears the active node, so merged data gets refreshed. - Add a regression unit test covering remerge behavior when focus moves from a child grid to the parent grid.
