Cannot use <nolink> in link fields in default content

I don't know why it thinks I made an MR. It is not my intention to work on this issue.

I did look at this page earlier. This isn't the first time D.o has randomly opened MRs on my behalf after I've glanced at an issue.

No worries @dcam happens all the time.

Am moving back to NW as there should be an MR and test

Is this the correct approach or are there other considerations or appraoches to fixing this that I didn't take into account?

Pipeline has issues, have not reviewed.

Using DDEV, follow the steps below to verify if the issue has been resolved:

Run the command: ddev drush php

Enter the following code:

$url = \Drupal\Core\Url::fromUri('internal:<nolink>');

The expected behavior is that no errors are thrown.

1) Drupal\Tests\Core\UrlTest::testFromRoutedPathWithNolinkRoute
InvalidArgumentException: The URI '<nolink>' is invalid. You must use a valid URI scheme.

ERRORS!

Removing test tag, rest seems fine too
