[Building Sakai] Samigo: Using <object/> tag in question text

[Shoji Kajita]

Dear Samigo developers,

We have been facing a problem that 

   <object/> tag in question text to play an audio file is removed

after our upgrade to Sakai 2.9.3 from 2.9.0-b06.

As far as I investigated, ItemAddListener is receiving the striped version of question text.

I think this is related to HTML sanitization but I couldn't find the code in Java and js.

Dones anyone give a pointer to address this issue?

Best regards,
Shoji
