Page Publishing is broken for logged in users

Found my issue.

In my theme, a really old piece of code adds the circle like the Air theme.

.published-page {
  &::before {
    background: linear-gradient(
      90deg,
      var(--tertiary-hover) 0%,
      var(--tertiary) 100%
    );
    clip-path: ellipse(148% 70% at 91% -14%);
    content: "";
    width: 100%;
    height: 100%;
    display: block;
    position: fixed;
    z-index: 0;
  }
  .background-container {
    display: none;
  }
}

I’ll remove it.
