.toolbar uses a z-index that can lead to undesirable overlapping.
See for example https://github.com/okfde/fragdenstaat_de/issues/157
This can be fixed by creating a new stacking context for .document.
A new stacking context could have been created with isolation: isolate,
but position: relative; z-index: 0; is more widely supported.
