Comment (by boonebgorges):

 In [changeset:"36784"]:
 {{{
 #!CommitTicketReference repository="" revision="36784"
 More specific test for a bad callback in `WP_Customize_Partial` test.

 The 'render_callback' passed to `WP_Customize_Partial` must either echo or
 return a result - not both. When it's detected that the callback echoes
 and
 returns a value, the return value takes precedence. This is now reflected
 in
 the corresponding unit test.

 Introduced in [36586].

 See #27355. See #36016.
