/**
 * This allows us to run any Drush command without modification against a
 * Playwright test instance.
 *
 * A first approach would guess that we could solve this only with changes in
 * settings.php. However, drupal_valid_test_ua() gets called before settings.php
 * is loaded, and it caches its result.
 *
 * A second approach would guess that a Drush command hook would allow us to
 * set $_COOKIE['SIMPLETEST_USER_AGENT'] early, before Drupal is bootstrapped,
 * allowing the test prefix to be set. Unfortunately, even the earliest command
 * hook won't work. That's because Drush creates a Request object with a
 * hardcoded empty cookie bin. Note the comment says to get request data from
 * globals for Drupal 10, but the Drupal 9 code is currently called as create()
 * still exists. Perhaps it was added back to Symfony? 🤷
 *
 * https://github.com/drush-ops/drush/blob/a34508223a80e42609544b4c9589ce09636e5a45/src/Boot/DrupalBoot8.php#L126-L134
 *
 * Finally, we land at this approach. By including bootstrap.inc, we can set the
 * static cache before drush has run at all. Then, our code in settings.php
 * works with zero modifications. Nice!
 *
 * One thing to remember when testing. drupal_valid_test_ua() only respects
 * cookie values less than 10 minutes old. If command start failing during
 * development, create a new cookie with task test:playwright:ua. Note this
 * isn't a problem for tests, since Playwright is configured to a 70-second test
 * timeout anyway.
