I wouldn't add another listener into the validate.js.
FWIW you can fix this issue by replacing this

with this:

    dialog.addEventListener('joomla-dialog:close', () => {
      window.removeEventListener('message', msgListener);
      dialog.destroy();
      this.dialog = null;
      this.inputName.focus();
      this.buttonSelect.focus();
    });

Basically it's a focus delegation problem...

@crimle @Nuyonuyonoina @eddiekonczal I will reset the negative test results as they are not caused by this PR. The PR modifies an NPM dependency, which can be seen by the label "NPM Resource Changed". Such PRs can't be tested with Patchtester, they require either a development environment with composer and NPM, or they need to be applied by using the packages created by drone, which can be found in the "Downloads" section of the integration checks at the bottom of the PR.
