SUMMARY


STEPS TO REPRODUCE
1. Add a Face Tag 
2. Type a few characters, e.g. "jo": a dropdown with auto completions opens
3. Using the down arrow key, navigate to the desired line in the auto completions, e.g. "John Doe" (at this point, the input field should pick up the current line)
4. Press Enter to save the face tag.

OBSERVED RESULT

The face tag is saved as "jo".

EXPECTED RESULT

The face tag should be saved as "John Doe".


SOFTWARE/OS VERSIONS
Linux: Debian 10
digiKam Version: 7.2.0-beta2 (Appimage)
KDE Frameworks Version: 5.74.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION

- The problem disappears when you use the mouse to select a line from the dropdown.
- This problem also occurs when editing an existing face tag, but only sometime:
  - It seems to work fine always when there's only one face tag in the picture
  - It seems to happen frequently (but not always) when editing the face tag with the focus on a picture with multiple face tags

This problem is rather annoying because you have to be very careful not to save face tags with wrong labels. Using "arrow down" to select a tag from the dropdown is very convient, but currently you have to double check your action every time and use the mouse if it didn't work out as expected.
