exit button

[EldrikFind]

Describe the Bug.

I went into the admin panel at the time when my Internet was not working (on a local project) and saw that instead of the blue exit button from the admin panel on the top right, I was displaying a broken image. I went into the html code and saw that this icon uses an image from the site at the following link https://www.gravatar.com/avatar/2d73d6fb831d1648336ef9e274127aac??default=mp&r=g&s=50. It is not clear why jpg is used in this place if svg is used in other places. I also see a potential problem in the future when the link changes that clients will be massively displayed an icon of a broken image since it is not entirely clear to me how gravatar.com is connected with payload and whether they will agree on changes to the link. I also see in issues that there have already been problems with this icon. As far as I understand from the site, gravatar is not a service for distributing icons. so I don't understand its use in this place why not use the standard svg icon

Reproduction Steps

open admin panel

Environment Info

payload

You can set a custom React component for the avatar in the admin panel, on the root Payload config:

(property) avatar?: "default" | "gravatar" | {
    Component: PayloadComponent;
} | undefined
Set account profile picture. Options: gravatar, default or a custom React component.

AFAIK, "default" currently just maps to "gravatar".

I understand that this can be changed independently, but why not make the icon the default. Also, it seems to me that this blue button looks a little out of place. Why not make a white circle, for example, and a black power-off sign in the center
