A cookie associated with a cross-site resource was set without the `SameSite` attribute
The warning messages specifically call out the domain that's responsible for the cookie. In this case, it's quilljs.com. If that's your domain, then you need to update the cookie there. If it's a third-party service that you rely on, then it's that service that needs to update their cookies.
