Created Unassigned: Context menu is mangled on the NumericUpDown controls. [22131]

The default style of TextAlignment="Right" on the NumericUpDown controls causes the context menu to be mangled. This issue applies also to the regular TextBox control, but there it can be fixed by using HorizontalContentAlignment instead - this solution doesn't work with the Extended WPF Toolkit's NumericUpDown controls.
