nav_to.do URL's will remove javascript: elements if the property "glide.script.use.sandbox" is not set to 'true'

When opening links to nav_to.do with javascript:xxxx elements, they are removed from the queries.

On sys_properties, set/create record with name glide.script.use.sandbox and value false

Opening the following link, it works:

• <instance>/incident_list.do?sysparm_query=assigned_to=javascript:gs.getUserID()

However, the following, it fails:

• <== PROBLEM
  -- <instance>/nav_to.do?uri=/incident_list.do?sysparm_query=assigned_to=javascript:gs.getUserID()      

Please set/create record with name glide.script.use.sandbox and value true
