Constraining drag not working correctly?

Describe the bug

Using chart.js 3.7.0, dragdata 2.2.4 Drag constrained by “onDrag” does not work as intended. If dragging a point, the constraint works as expected DURING drag (point keeps glued to upper/lower limit), but on dragEnd - if the cursor is beyond a limit - the point suddenly jumps to a “forbidden” value

To Reproduce I have the code (line chart) in a public github Also on stackblitz

The constraint of the drag is done via (index.ts:403) :

onDrag: function (e, datasetIndex, index, value: number | Point) {
      e.target.style.cursor = 'grabbing';
          if (typeof value === 'number') {
            return value >= 2 && value <= 19;
          }
          return value.y >= 2 && value.y <= 19;
        },

Expected behavior

If beyond a limit point during drag, the point shall stay there, regardless if the cursor moved further beyond on dragEnd.

Alright, I now made a minor change creating a deep copy of the original data object. That solves the bug on my end, would be nice if you could confirm! chartjs-plugin_dragdata-v2.2.5_beta.zip

The flat copy may have the benefit of not stripping any getters/setters from the original object. Not sure if it’s a common pattern to use them in this context but I guess it could be annoying if the plug-in would unintentionally remove those
