When leveraging the iCS (interplot) service, background masking is not being honoured on the element type "Text Node". Element type "Text" works as expected.
The reason that text nodes are being used is that when the user applies a field to a text string, the application converts to a text node.
We require a setting or a change to the system to recognise a text node as a text element with the associated masking settings as it currently does on desktop rendition delivery.
