Issues on "multiSelect=false"

I’ve added it to our Github board cause it’s related to Handsontable (not a PRO feature) at: https://github.com/handsontable/handsontable/issues/3250
It is a low mischievousness for the table that is why I can’t guarantee any quick solution.

There’s no value transfer after dragging it only doesn’t look pleasant, am I right?
