Dashboard main container size gets changed

[bfbones]

Environment

Nextcloud 20.0.4 Vivaldi 3.5 / Fedora

Description

Using this addon the dashboard container size gets changed and its background accordingly. Content is missing in height and the design seems broken.

Screenshot

Affected code

# css/dashboard.css
body {
        height: auto;
        min-height: 100%;
}

If this code gets simply removed it works just fine. This problem also exists for https://github.com/nextcloud/integration_github
