Additional Info:
This is related to bug 89604 I filed, that was marked as duplicate of bug 81643 that was closed recently. Maybe the last commit resolved Calc issues, but for Writer it made it worse. So I filed a new bug with this.
I noticed that in the context help text that this borders options apply to Writer and Calc.
