beforeKeyDown event -> stopImmediatePropagation is not working

[arfis]

Using the beforeKeyDown event for deactivating the key movement in the table, does not work. The beforeKeyDown emitter returns an array of keyEvents. When trying to call stopImmediatePropagation on the returned events, nothing happens and it is still possible to move in the table.

@arfis, please check if this is an issue with Handsontable itself, e.g., by editing their example on JSFiddle. If it is a Handsontable issue rather than a problem with our wrapper, please post it on the Handsontable issue tracker.
