UMG Background Blur black in blueprints

[Hover]

If I attach a UMG Widget including a Background Blur Widget to a blueprint it renders black.

Why is that?

Steps to reproduce:

1. Create an UMG widget
2. Add a background blur widget
3. Create an empty blueprint
4. Add a “Widget” to it.
5. Select your UMG widget as the class
