Replace geometry: keyboard friendly conflict resolution

[bagage]

What steps will reproduce the problem?

1. Create a way building=yes and a node building=church
2. Try to use "Replace geometry" tool

What is the expected result?

A conflicts dialog must appear. Possible values for building tag should be listed: church or yes. You should be able to select your choice ("church" or "yes") via keyboard (similarly to changeset conflict dialog).

What happens instead?

You have to mouse over building value, click then select an element in the provided list (church, yes, none, all). Finally close the popup. Lots of mouse movements needed :/.

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