Hi all,
I hope this has not been reported before but I've found that the recent citation picker rework has introduced some probably unwanted behaviour. To reproduce:

1) In a LO document, open the citation picker and select a citation. Add it to the document.

2) Move the cursor into the newly created citation to edit it. In the citation picker window click on the blue bubble to edit details and add a sufix or prefix. Press enter to confirm and close the popup.

3) Press Enter to finish editing.

Result: Instead of closing the citation picker and confirming the changes, Enter adds the first result from the dropdown. In this scenario (having edited an existing citation) this is almost certainly not what anyone wants. To close the dialog on has to remove the newly added citation and after that pressing enter closes it.
