Data Grid Observable Row Drag and Drop Malfunction

Hello,


for our application we need an Data Grid using the row drag and drop feature for sorting rows within a grid. This works like a charm when using normal Lists as data source. As soon as we use an Observable Collection instead of a list as data source we run into issues.


I've attached a sample project for our issue. The index page contains two data grids with either an List or an Observable Collection of an class instance. When changing row order by drag and drop multiple issues occur on the observable data grid. Partially rows are deleted or copied.


We updated our dependency from version 21.2.8 to 22.2.5. Beforehand row drag and drop on observable collections worked fine.


Thank you for your help


Regards Luis D.
