Wrong key+tag pair opened when clicking Edit button, when keys list is not listed in alphabetical order by keys.

[nagy_balint@…]

What steps will reproduce the problem?

1. Choose an object with multiple tags and keys.
2. Change list of tags in reverse alphabetical order (from z to a).
3. Select one key+tag pair.
4. Click edit button.

What is the expected result?

Dialog window to change the choosen tag or the key.

What happens instead?

The program opens other key+tag pair.
It seems, that the program doesn't recognise that tags and keys are in reverse alphabetical order. If you choose and try to edit the 3rd key+tag pair in the reversed alphabetical list, it will show the tag+key pair which is the 3rd in the list of the normal alphabetical order.
There is 4 ways to change the list of the tag+key groups. Normal, and reverse alphabetical order regarding to the key or the tag. It seems, that the change of this list doesn't effects the "Edit" button. If you try the 2nd key+tag pair on the list, you'll be able to change the one pair, which would be the 2nd in the list of alphabetical order by keys.

Please provide any additional information below. Attach a screenshot if possible.
