FilteredSelectMultiple Widget Not Functional in Inline Formset After Form Deletion

Description

In the Django admin interface, when using an inline formset that includes a FilteredSelectMultiple widget,
deleting a form causes the FilteredSelectMultiple widget below the deleted form to become non-functional.

It appears that this issue may stem from how the id attribute index is dynamically updated when forms are added or deleted.
The SelectFilter event listener seems to register the initial id at the time of SelectFilter creation.
When the id changes, the event listener does not update, which causes the filter functionality to break.

Steps to Reproduce:

  1. Open an inline formset in the Django admin that contains a FilteredSelectMultiple widget.
  2. Delete one of the forms within the inline formset.
  3. Observe that the FilteredSelectMultiple widget below the deleted form no longer functions correctly, with the filtering feature disabled.
