We've noticed that the Hybrid Login block displays a header at the bottom of the custom block template:
{% if hide_drupal_login == 0 %}
<hr>
<h2>Sign in with existing account</h2>
{% endif %}
This made sense at first when you have a vertical layout for the Drupal login page, but if a site wanted a horizontal split layout it wouldn't display correctly. This title probably shouldn't be managed in this block, but rather in a login form template outside of the Hybrid Login module.
Simply remove the code snippet above from the template file located in templates/hybrid-login-block.html.twig

Hey @jminarick, this makes sense. Better to let the theme / individual site owner decide how to deal with that header. Looks good.
