Pull request overview
Fixes a virtualization/navigation edge case in IgxGrid where vertical scrolling can leave NgZone already stable, preventing the chunkLoad emission and causing keyboard navigation (arrow keys) to stop working after a vertical scroll.
Changes:
- Refactored the vertical scroll stabilization logic into a reusable callback.
- Added an
NgZone.isStablefast-path to rundetectChanges()and emitchunkLoadimmediately when the zone is already stable. - Kept the existing
zone.onStable.pipe(first())path for non-stable cases.
