Fixes #1928

Summary

Fix copy-button interactions in the animation list.

Changes

• Use e.target.closest('.copy-icon') in docs/modules/playground.mjs so clicking the tooltip can still resolve the corresponding copy button and copy the animation class.
• Scope the tooltip lookup in docs/main.mjs to the current copy button with icon.querySelector('.tooltip').

Why not use pointer-events: none?

The first suggested fix disables pointer events on .tooltip. This was not used because the tooltip overlaps the animation title area. Clicking the left side of the tooltip can then pass through to the animation title and trigger the animation.

Using closest('.copy-icon') keeps tooltip clicks associated with the copy button without relying on pointer-event pass-through.

Validation

• Verified that only docs/modules/playground.mjs and docs/main.mjs were modified.
• Passed JavaScript syntax checks with node --check.
• Passed git diff --check.
