### Steps to reproduce

* In a document, insert a work package either by creating a new one or adding an existing one


### What is the buggy behavior?

* The background of the work package block seems to come from a Mantine variable, which resolves to _#EBECED_ in regular light mode.


### Expected behaviour

* The background should be lighter, ideally as close to `bgColor-muted` Begin of the insertionpossible. In Primer, this resolves to:

* End of the insertion Begin of the deletion possible (that resolvedEnd of the deletion in regular light Begin of the insertionmode: #f6f8fa

* End of the insertion Begin of the deletion mode to _#F6F8FA)._


### Attention
