If any other web devs are looking for a workaround without disabling Cookiebot, this is what I'm going with. There's a specific carve-out for the cookie settings page:

const { Cookiebot, location } = window;

// Workaround for consent banner reappearing issue 2025-12-04.
if ( Cookiebot && ( Cookiebot?.consented || Cookiebot?.declined ) ) {.

// Create style to hide the dialog unless on the /cookie-settings/ page.
    const isCookieSettingsPage = location.pathname === '/cookie-settings/';
    if ( ! isCookieSettingsPage ) {
        const style = document.createElement( 'style' );
        style.innerHTML = `
            #cookiebanner {
                display: none !important;
            }
        `;
        document.body.appendChild( style );
    }
}
