Error when dragging columns in pivot field list Declined - Cannot Reproduce

Hello,

We are experiencing an error with some data sets when we try to drag a column from the pivot field list onto one of the axes (Filter/Columns/Rows/Values). It seems that it does not matter which column is dragged nor does it matter which axis it is dropped onto. This is not occurring for all data sets but in my experience it is happening with about 80% of them and it does happen consistently with the same data sets. We use dynamic data sets so we do not have set columns in the grid; we let the control create the columns for us.

This didn't use to happen so it looks like an update at some point in the past few months may have introduced this. I am going to look at downgrading until I can determine which version introduced the problem.

The behavior is that the spinner icon displays in the middle of the field list and the dragged column continues to display. The cursor is the red circle with a line through it. It does not change unless I refresh the page:

The console displays the following error:

Clicking on the top level of the stack shows the error is happening in the control's code here:

Unfortunately I don't know what to do to correct this. I have tried to look for commonalities between the data sets that work and those that don't. The number of rows in the data, special characters in the names of the columns, etc. don't seem to be a factor.

As mentioned, I will try to downgrade my controls to see if there is a version this doesn't happen in to see if that helps you narrow down the root cause. I will update this ticket if I have more information. Right now this is a show-stopper because the control freezes up and does not allow the user to create their data sets in the pivot grid.
