Describe the bug Just wanted to report the return of the old bug that »white« objects are black after export/print, which occured several times before already, in the current version (see below). Which means, that »white« elements (dark theme enabled) are by default using the color »F0F0F0« but are black after export/print. Setting it to pure white like »FFFFFF« (or any other color) works, so this maybe is also again related to the dark them issues from the past. This means, that all elements need to become an explicitely defined custom color even though F0F0F0 (and maybe there is a reason, this is the default color)is visually fine as »white« the same as FFFFFF is. But for just a quick diagram, this is unnecessarily complicated. Same for the default »black«.

To Reproduce Steps to reproduce the behavior:

1. Place an object with the default colors into the document
2. Eport (for example as PDF) or print the document

Expected behavior Obvious.
