AT:
- show loading indicator when a diagram is being loaded/rendered. Especially
- in the branch analysis
- flow node filter
- heatmap reports in report builder
- the process definition selection in the report builder
- the dashboard that contains a heatmap report
Context:
Large diagrams take a long time to be rendered. The reason is that it takes a long time to parse those diagram. However, during the parsing time there is nothing shown in Optimize. So the user does not know that the diagram is actually being loaded.
