Spot on, elements in the defs section do not have an associated
GraphicsNode, so there is no bounds to provide. The main issue here
is that when an element is 'use'd it actually get's it's CSS properties

could be different.

You need to copy/put the text element into part of the rendering
tree (probably with visibility=hidden).
