[CustomCellFactory] comboBox and choiceBox don't receive focus on editing

I apply custom cell comboBox factory to listView and got a possibility to change value of list item by chosing it from comboBox. In theory, if I press F4/alt+up/down I got an opened popup window with focus there.

In practice: I select list item using up/down. Press F2 to move it to editable state, and I want to press F4 but selection is on listItem. So events come to listView, I think, but not to the comboBox.
