Currently the DMN designer shows the inline context menu after the left mouse button click. However I think th menu should be displayed after the right mouse button click as the current behavior causes problems in 2 important situations:

1. User wants to edit the cell value. This is done with left mouse button double click. Very often the double click does not invoke the cell editor but the inline context menu is just shown.
2. User wants to drag the the table row
   1. Point mouse to proper row number
   2. Press and hold left mouse button
   3. Drag the row
   4. Relese the left mouse button
   5. The inline context menu is shown in this moment what is probably not expected
