Rendering issue when using '&timestamp' on the Active Docs from Red Hat 3scale API Management

Issue

We have an endpoint that returns a URL inside the JSON response. The URL includes two parameters, including timestamp. The correct response is:

{
 "link": "https://my.domain.com?user_key=<USER KEY>&timestamp=1234567890"
}

When we call this service from the Active Docs in the Developer Portal, this response is displayed:

{
 "link": "https://my.domain.com?user_key=<USER KEY>xtamp=1234567890"
}

Apparently 3scale code considers &times as the HTML code × so it replaces the string with the multiplication operator x.
