Message:

Interactivity API: Allow server derived state to appear in non-final position

In some cases, derived state returns an associative array. Directives may wish to continue to access properties of the associative array, when using the syntax state.arrayReturnedByClosure.property. This patch continues evaluating the path after the associative array has been returned by the Closure.

Props jonsurrell, luisherranz.

Fixes #61741.
