What is the current behavior?

When rendering a PieChart with animation enabled:

• Without <Legend />:

  • Animation runs correctly
  • onAnimationEnd fires after animation completes

• With <Legend />:

  • Animation is skipped
  • onAnimationEnd fires immediately

What is the expected behavior?

• Animation should run normally regardless of whether <Legend /> is present
• onAnimationEnd should fire only after animation completes
• Adding <Legend /> should not affect animation lifecycle or timing

Please provide a demo of the problem in a sandbox
