Capital D in Add node dialog

[GerdP]

What steps will reproduce the problem?

1. Not sure when exactly this happens, but sometimes pressing Shift+D results not only

in the add node popup, but also the lat/lon field is filled with "D"

What is the expected result?

Shift+D should only open the dialog, it should not be registered as input

What happens instead?

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

In 15053/josm:

fix #17682 - run AddNodeAction later in EDT to make sure the KeyEvent triggering it is consumed before the dialog is shown
