Pressing Esc when adding link also dismisses edit popup

Question

When you press Esc on an editor popup while in an edit dialog, the popup is closed.

Steps to reproduce:

• Find a post with a suggested edit
• Click the edit(1) link
• Click Improve
• Use the editor to add a link
• Press Esc to cancel adding a link
• The whole Improve dialog gets removed, including all of the changes I've made. It should only remove the dialog to add a link.

Obviously, the same thing happens when you upload an image.
