This is corollary of DROOLS-3652 where enhancements of keyboard control for Name and DataType popover were implemented. However also an inconsistency was introduced.

We have three cases when Name and DataType popover is shown:

• Click on header cell
• Enter when header cell is selected
• New context entry, DT column, relation column ... is added

The inconsistency is between first two cases and the last one. When the popover is shown for first two cases, Name input field has focus, however in the third case, no element in popover has a focus. We should consolidate the behavior for all three cases.
