Single-click on server-side decorations causes window to enter drag mode

Probably the worst demonstration of all time, but here:

Let me know if this is a duplicate issue!

I think it detects the start of a drag based on a threshold of a certain number of pixels moved after the click, so maybe that number should be increased. (Or I don't know if there are other checks that other implementations use.)

I was clicking, then lifting my mouse click without moving my mouse at all, which was what struck out to me. If it's calculating a threshold, yeah it definitely should be increased.

I don't know how other implementations work for sure, but if the mouse is lifted it probably shouldn't keep the drag going

[ids1024]

Oh yeah, it shouldn't keep dragging after lifting the mouse. That should cancel the mouse grab and stop the drag.

Probably something #1046 broke.
