overflow for symbol
overflow of a symbol is set to inherit.
Therefore the overflow property is inherited from the
referencing use element, scroll/hidden on the left, auto/visible on the right.
The area for the symbol defined by a use element is indicated with thin
black stroked rectangles, if clipped, fragments of the symbol are only inside this
rectangle.
