[Accordion] Opening animation isn't cancelled when a panel is initially open

[mj12albert]

Repro: https://codesandbox.io/p/sandbox/eloquent-gwen-dpp375

Tested with transitions but likely to happen with animations as well, the underlying collapsible's open state can't be determined before the first render when all the panels are indexed and the accordion's value prop ['value'] can be resolved to the panel's initial states

[mj12albert]

A workaround is to explicitly set the value prop on accordion items, even if it's just the index:

<Accordion.Root defaultValue={[0]}>
  <Accordion.Item value={0} / >
  <Accordion.Item value={1} / >
</Accordion.Root>

{/* or */} 

<Accordion.Root defaultValue={['settings']}>
  <Accordion.Item value="home" / >
  <Accordion.Item value="settings" / >
</Accordion.Root>

In Radix, the item's value is a required prop: https://www.radix-ui.com/primitives/docs/components/accordion#item
