When parsing the AuResponses to handle echo events, if the generated source zul contains an include element that contains javascript code, the json parsing fails (org.zkoss.zats.mimic.impl.au.AuUtility#parseAuResponseFromLayout(String)).
This is caused by the nested javascript in the generated json object and is not fixed by ZATS-34, although the issue is related to it.
A unit test case to reproduce the issue is attached.
