-----------------------------+-----------------------------
 The changes to the `locate_template()` function in
 https://core.trac.wordpress.org/changeset/56635 that replaced
 STYLESHEETPATH and TEMPLATEPATH constants with the relevant functions have
 broken the `get_template_part()` functionality in a multisite network that
 uses `switch_to_blog()`.

 Expected behavior: `get_template_part()` should only look in the active
 theme of the current site even after `switch_to_blog()` is used.

 In WP 6.4.2, if `switch_to_blog(1)` is used in site 2, then
 `get_template_part()` is called, only the active theme of site 1 is
 searched for the template part. `switch_to_blog()` should only affect
 database calls and should not allow theme developers to pull template
 parts from the theme of another site in a network.
