Could you clarify the testing instructions? Is this one where you have to download the code with the patch applied and then do a new Joomla install? I have never done one of those so will probably leave it to others to test.

To use the patch tester its required to have an installed Joomla instance. To test this PR you need the installation application -> patch tester not working
Its better to use the prebuild package or checkout the git branch (needs composer/npm ...)

The old and new line is not needed at all as we already load the validate script in the main template file

joomla-cms/installation/template/index.php

Line 23 in 027892a

->useScript('form.validate')

As @brianteeman says, the ines can be removed completely.

Done. Didn't notice that it was already loaded.
