Strange bug(?) when I push enter to see a varchar field's text

I experienced a strange thing from the previous 2-3-4 versions.

Query, result grid.

Formerly when I pushed Enter key on a string field an popup editor appeared to modify, or see the content.

Now the Enter key creates an extra, half empty row, and opens the editor popup.

I can't close this editor by canceling or reopening the query. It remains. I can close it when I close the Query tab too.

Double mouse click works well, only the Enter changed somehow.

Do you also experience the same problem?

Thanks:
