==== Typical errors ====
  * ''Cannot read properties of null (reading 'classList')''
    * Caused by bootstrap5-plugin: this requires the form-control to be embedded in a ''.row'' div > the .row div will contain the ''.fv-plugins-bootstrap5-row-invalid'' style and add a ''.fv-plugins-message-container.invalid-feedback'' div to the bottom of the row.
