pub fn to_self_alignment( self, axis: LogicalAxis, cb_wm: &WritingMode, ) -> Option<AlignFlags>

Returns a value for the self-alignment properties in order to resolve normal, in terms of the containing block’s writing mode.

Note that the caller must have converted the position-area to physical values.
