Logo in nav (hidden?) behind sidenav

[Mellmountain]

Describe the bug

I'm trying to get a logo to show up in the nav-bar. It successfully shows on the 'home' layout but not on the default layout (doc). After some experimenting I think that the logo is behind the sidenav (see attached image).

my config.mts -file

themeConfig: {
    siteTitle: 'My uneccesary long side title',
    logo: {
      dark: '/logo-dark.svg',
      light: '/logo-light.svg',
    }

Reproduction

Not sure how to reproduce. Have not gotten it to work yet :(

Expected behavior

Logo is shown in the doc layout.

I feel really stupid but I had loaded a custom css-file that manipulated the z-index. Once fixed the logo showed up as expected.
