complex jsxgraph snippets cannot be edited after they are created

[kosmicunifr]

we have experienced problems with some complex jsxgraph code snippets. when you create a new page component and paste the jsx code into it, everything is fine.
when a user then tried to edit the code again, the preview is not shown, the code is truncated and trying to save it again leads to ILIAS errors being thrown about errors in the DOM / XML structure.

Is it possible to attache one of the breaking examples to this bug, since I am not able to reproduce your issue. I useed http://jsxgraph.uni-bayreuth.de/wiki/index.php/Three_touching_circles and it worked without any issues.
