Comment (by westonruter):

 In [changeset:"39241"]:
 {{{
 #!CommitTicketReference repository="" revision="39241"
 Customize: Allow starter content to apply in a new theme when switching
 from another theme containing changes.

 * Ensure that starter content can apply from theme B after previewing
 starter content in theme A.
 * Introduce new `starter_content` flag in changeset setting params which
 is used to capture whether a value is starter content and thus can be
 overridden.
 * Create changeset up-front with `starter_content` flags instead of
 waiting for `AUTOSAVE_INTERVAL`.
 * Eliminate instantiation of settings for widget instances in favor of
 directly calling `sanitize_widget_js_instance`. This eliminates issues
 with looking for widgets before they are registered.
 * Ensure that non-placeholders (inline arrays instead of string
 references) can be supplied in starter content.
 * Re-use auto-draft posts as starter content across theme switches.
 * Introduce `starter_content` param for
 `WP_Customize_Manager::save_changeset_post()` which is `false` except when
 starter content is being loaded on a `fresh_site`.

 See #38114.
 Fixes #38541.
