Fixed DIV-Container IDs for Visualizations Merged

We are using CSS to customize the appearance of our reports. Since the individual DIV Containers do not have a fixed ID but get a random one each time you open the anlysis file or switch to another page we have to use the order of DIVs to e.g. make the background transparent. When the layout changes, for example with the mobile layout or when maximizing a visualization the order changes and corrupts the style.

As a fix we would require constant DIV IDs so we can refer to always the same ID instead of relying on the order.

This might also be helpful if Tibco wants to expant on the topic of custom themes to address individual visualizations.
