Switching between area style sections (previously called and implemented as tabs) the origin color changes from the initial value to what is set at new. The origin color value should remain as long the dialog is open.
I think I fixed this one in https://cgit.freedesktop.org/libreoffice/core/commit/?id=cc2d27ea1ef4018d0865095853e7d661f8070e1f
In this version already
Thanks a lot, that makes the process more clear. You can now modify the color and if you switch to another tab the values are discarded and when coming back the active color is used. No warning, though, which is consistent with the other sections.
A likely unrelated observation: Starting the area dialog with blank paragraph settings shows black in the active color but values from the current color (or what I had there before).
