Codeigniter 4 debug bar header link "disappeared" - color won't change

I figured it out by methodically commenting 4000 lines of our CSS to narrow it down.  Looks like it was the code for the h1 moving the links.  I'm not sure the best way to go about fixing this, as I don't really want to update the CI4 code and we have a lot of h1's through out our very large site.
h1{

    font-size:1.8em;
    font-weight:400;
    font-family:'Open Sans', Sans-serif;
    text-transform: uppercase;
    color: #464646;
    background-color: #f4f9eb;
    padding: 1.4em 0 1.4em 20px;
    margin: 0 0 1em;
}
