[BUG] Animate mini crash when cancelling scroll

[bakura10]

Hi,

When using animateMini with scroll, trying to cancel the function to clean up scroll listeners will raise an error, causing Motion Mini to crash.

The issue can be reproduced here: https://codesandbox.io/p/devbox/vanilla-js-forked-gg4wq9?workspaceId=ws_2ajUMWBiBa7sDb8MJCFnBo

For now, the only workaround I have found is to check if the element is visible in the DOM, but this means that removing scroll listeners in a disconnectedCallback is not possible.

Thanks.
