Ensures event stacking only occurs when events actually overlap in pixel space, preventing visual artifacts. Breaks stacking chains when events no longer overlap due to middle element removal, and correctly resets styling.
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.
