I've successfully extended the RTE of a client solution with the Wiris math plugin, but I have one problem that I've been unable to solve. 

Saving an item that utilizes the plugin in the RTE results in escaping the Wiris injected values.

I'd like to avoid having to dig through the Umbraco js to find what's happening. Has anyone tried integrating Wiris before? Any ideas on how to approach this instead of a brute approach debigging the js?
