Generally, it's possible to drag a TS window to another monitor, but, there's a bug with the "semi-transparent dragging mode", which turns on whenever you drag a window in 2 opposite directions.
In the single monitor mode it causes no issues.
But in multi-monitor mode it causes the window to jump to monitor 1 after you finish drag'n'dropping of a TS window that switched to "semi-transparent dragging mode while it was dragged".

Yet, sometimes the issue doesn't happen at all.
