When you add a face tag in album view, typing a name does not show the list of similar tags, like it does in face detection pane: this forces you to type the whole name instead of clicking on the suggestion list. Instead, it shows the full list of tags: first, the combo is too little, and anyway the full list of tags (with tree view) is pretty useless in that context. Reproducible: Always
