The behaviour appears to be affected by size of the svg document not the element size.  Which means the effect depends on which theme you start out with:
* Starting out with Oxygen, Clean Blend or Slim Glow, changing to any other theme works fine.
* Starting out with Aya, changing to any other theme except Silicon exhibits the behavior to varying degree (from large to HUGE)
* Starting out with Silicon, changing to any other theme except Aya exhibits the behavior to varying degree (from large to HUGE)

In all cases, a restart after the theme change makes everything look fine.

I altered the document size, then the element size, then both for the extender-dragger of the Aya theme and tested for each case.  The closer the document size is to the extender-dragger of theme being changed to, the less the problem.  I see the use of renderer->defaultSize() in Plasma::Svg which the QT Docs say is default size of the document contents.  I'm not sure I understand exactly how or why it's used enough to attempt a fix.

I wonder if this is the same problem that causes the clock hands to get big when changing between themes.

Hope this helps,
