I was running into a problem with a popup menu control in a dialog; clicks weren't working (but keyboard was working fine). It turned out that the menu was getting destroyed before the click event could fire. Tracked down the issue to the way draggable blurs focused controls; it was doing the blur before it ran through the logic to figure out if the drag was actually on the handle. I've moved the blur below these checks, so it'll only blur things if it actually needs to handle the drag. Otherwise, it asserts no opinion on what should and shouldn't be focused, which seems like the way things ought to be. Also, added a unit test to check for the expected behavior. Fixes #15046 Closes gh-1730
