Quill link dialog (righly) escapes quotes in URL values there by breaking the
TrackLink() template function. That is, {{ TrackLink "https://listmonk.app" }}
when inserted using the Quill link dialog would become
{{ TrackLink "https://listmonk.app" }}. A simplework around is to
add support to backticks so that the template parser works with
{{ TrackLink `https://listmonk.app` }}
