Pull Request Overview

This PR modernizes the codebase by replacing the deprecated isSameNode() method with the === strict equality operator for DOM node comparisons. The isSameNode() method was deprecated in DOM Level 4 and the === operator provides the same functionality for node identity checks.

• Replace all instances of element.isSameNode(otherElement) with element === otherElement
• Update negated comparisons from !element.isSameNode(otherElement) to element !== otherElement
• Add parentheses around complex expressions for clarity and precedence
