Refactors event overlap handling to use a DOM-centric approach with data attributes for stack tracking. This eliminates complex state management, reduces code complexity, and improves maintainability. Removes the previous Map-based linked list implementation.
The new approach offers better debugging, automatic memory management, and eliminates state synchronization bugs.
The solution maintains identical functionality with a significantly simpler implementation, focusing on DOM manipulation for visual stacking and column sharing.
Addresses potential performance concerns of DOM queries by scoping them to specific containers.
