Comment:

 There is some overlap with #50639 here, moving to the milestone to address
 one way or another.

 Looking at the [https://travis-ci.com/github/WordPress/wordpress-
 develop/jobs/385374984 current test failures], quite a few are caused by
 [https://github.com/WordPress/wpdev-docker-
 images/blob/84a4acfc15fd0bff04e3342e5c24a2c0ce5211cf/update.php#L181
 missing 'gd' extension] in the [https://github.com/WordPress/wpdev-docker-
 images WP Docker image]. That includes tests explicitly checking for
 `imagejpeg()` and failing with "jpeg support unavailable", as well as
 tests implicitly relying on GD availability without specifically checking
 for it, causing more obscure failures.

 The Docker image should probably be updated to provide the same list of
 extensions for PHP 8 that we currently have for PHP 7.4 and older: `gd`,
 `opcache`, `mysqli`, `zip`, `exif`, `intl`, `mbstring`, `xml`, `xsl`. If
 anyone is able to help with that and open a PR, please do :)

 Still, explicitly requiring `imagejpeg()` and related functions as
 outlined in comment:3:ticket:50639 would be better than the current
 obscure failures. So consistently requiring GD functions where needed
 seems like the next step here. Where that means failing or skipping the
 test, can be determined later.
