OpenContextMenu on grid throws error since version > 20.4.0.44

[Sheldon]

A fairly simple grid with a context menu which was working fine and still works ok if I roll back to 20.4.0.44 now throws an unexpected error. Here is the grid:

<SfGrid ID="ContainerGrid3" @ref="gridRefs[2]" EnableAdaptiveUI="true" AdaptiveUIMode="AdaptiveMode.Mobile" RowRenderingMode="@(_isSmall ?
