Thrown by forty-cdk/drawer.
[forty-cdk/drawer] FORCDK-DRAWER-001: A parent drawer was destroyed while a nested child drawer was still registered.
Cause
The drawer stack unwinds last-in-first-out, so a child must unmount before its parent. Sibling @if blocks unmount in template order instead.
Fix
Wrap the child drawer's @if inside the parent's, so the child unmounts first.
