user_created and user_updated events not triggered at all in user/editadvanced.php
Think this was an oversight in MDL-45641

• see following in 2.7.1 /user/editadvanced.php (missing from 2.6.4)

  255 // Trigger update/create event, after all fields are stored.

  256 if ($usercreated) {

  257 \core\event\user_created::create_from_userid($usernew->id)->trigger();

  258 } else {

  259 \core\event\user_updated::create_from_userid($usernew->id)->trigger();

  260 }
