## Description
Closes#6760
The `withinCollapsible` prop from the `useCollapsible()` provider is
always returning false.
This bug originated from [this
change](https://github.com/payloadcms/payload/pull/6666) from me - in a
previous issue, the provider was always returning `withinCollapsible:
true`.
Previous fix was not correct, the `withinCollapsible` should be `false`
when creating the initial context, and then be `true` when it is
de-structured in the provider. Tested with tabs, arrays, and groups. All
working as expected now.
