Weird ENTER key behavior in Inline Edit with selectType = Cell

[mkaramizrakli]

Hi all, not sure this is the right place to ask this, but I have a problem with w2grid in Inline Edit mode, when selectType is set to "CELL".
I want to enter to edit mode using the ENTER key. It works for the first time, but when I move to next column using arrow keys and click ENTER again, the previous column is being edited.

Here is the link for the fiddle: https://jsfiddle.net/mkaramizrakli/grqzuLhj/11/

Thanks in advance!
