Grid cell multiselect

How can i apply the selected items from the cell dropdown upon pressing Enter. Currently when i press Enter the selection disappears and the only way to apply the selection is to click away which is… not ok.

Any solution to disable this genius default implementation? What i want is when the “enter” is pressed to keep the currently applied items from the multiselect dropdown combo and close the combo + triggering the events which would get clicked if u click away to apply the changes (the way it is implemented currently).
