I don't know the cause and if this is possible but just a quick check
at the svgio code my speculation is that it could make a difference if
it determines for example that text overflows the bounds and it needs
to clip. If you look at the XML and what the test checks you see the
mask primitive is inserted just suddenly. I saw in the svgio code that
the mask primitive is used at many places to do clipping.

The XML from primitive dumping is really basic here so not a lot of
info which would be useful is available (transform, mask has no
attributes) so it would be useful to see these values..

You need insert the SVG as you would insert any other image to use
this SVG parser.
