Comment (by SergeyBiryukov):

 In [changeset:"49039" 49039]:
 {{{
 #!CommitTicketReference repository="" revision="49039"
 Build/Test Tools: Use trunk revision 2387243 of the WordPress Importer
 plugin.

 This revision includes a change to only call
 `libxml_disable_entity_loader()` in PHP < 8, in order for unit tests in
 the `import` group to pass on PHP 8.

 This function has been deprecated in PHP 8.0 because in libxml 2.9.0,
 external entity loading is disabled by default, so this function is no
 longer needed to protect against XXE attacks.

 Follow-up to [46542], [48789].

 Props jrf.
 See #50913.
