Hi,As far as I am aware data elements never had access to the `event`.
The `event` is sent to conditions and action modules. The JavaScript
data element reads the values from the `window` object. When you create
a JavaScript data element with `event.detail.myproperty`, it is
translated to `window.event.detail.myproperty`. Are you sure you didn't
have maybe a piece of code that was setting the `window.event` property?
UPDATE: I was wrong, it seems data elements modules have access to the
`event`....
