When I close as duplicate, I want to be able to drag a link from a different place (The comments, the Related Questions section, another page), directly into the close as duplicate dialog. Currently, the result is that the placeholder remains (until I click elsewhere), the link is pasted inside the textbox, however, the question isn't loaded.
In order to fix it, I need to, while focused on the text input, hit any button.
My (educated) guess is that it works based on a
keydown event. Can we please change it to
input event, like the post editor?
