Default logo is not shown

[MorrisJobke]

@juliushaertl Do you remember that the logo in my instance is not shown? The --image-logo css variable resolves to core/img/logo.svg, which isn't there.

server/core/css/variables.scss

Line 64 in 8054368

$image-logo: url('../img/logo.svg?v=1') !default;

To reproduce one needs to disable the theming app. 😉
