DM 4.0 M8: Is there a way to show UML symbols with customized views in the web client?

Hi,

we have used the org.eclipse.gmf.runtime.diagram.core.viewProviders extension point on the RSA side to change the appearance of UML Class symbols with our stereotypes applied. When looking at a diagram containing such symbols in the web client I get red squares annotated with "invalid view - remove from diagram". Will DM be able to show these symbols at some stage, even if just with the standard Class symbol? Is there something I can do to make these symbols appear? Attaching images to point out the problem.
