Indeed, I did not found this particular thread, but I have come across the fact that it was supported in the past. I guess my solution will also be a bit fragile, but so far, it works :)

I was also contemplating removing the borders and title bar of the floating window, so that it would much more like a panel, but on Windows, Chrome actually draws its own title bar, so you cannot remove it using the Windows API.
