[unity8] can't drag child window back into main GUI

[dinamic]

ubuntu 17.04 unity8. see the screenshot first.

install tiled (qt app) "apt install tiled"
launch tiled
in tiled you can move the gui elements arround, drag one of the tabs out of main window "Mini-map" "Objects" "Tilesets" "Terrains" or whatever. it will pop out of main window into a child window. now move the tab at the previous position in the main window by drag and droping it. you can't because there is no way to move or close the child window.

in unity7 the child window is dragable and i can put the window back, see attached screenshot on unity7

looks like in u8 it's missing the "custom?" title bar?

Try Alt+drag with the mouse?

If the child window is draggable without using Alt in Unity7 then this is a duplicate of bug 1420334.

testing with silo 2481, deatached tabs are not dragable with ALT drag, ALT draging other child windows works fine

@daniel in unity7 are dragable without Alt, but they also have a title bar that is missing on Unity8 (see in the screenshots)
