[Bug] Window Drag Misbehavior Across Virtual Desktops with "Alt + Drag" and "Auto Activate" Enabled

[Glitchy-Sheep]

First of all, thank you very much for such a good software, I love it, it solves so many tasks of mine. It replaces so much ahk scripts all over my system. 💖

Describe the bug There is a misbehavior in "window drag with alt" and "automatically activate the moved window" turned on.

Sometimes when I move from one desktop to another and try to move specific window the FancyWM "thinks" that I still on the first desktop and drag windows from there.

To Reproduce Steps to reproduce the behavior: 0. Create 2-3 virtual desktops before start

1. Enable Interaction -> Move windows by holding Alt
2. Enable Interaction -> Automatically activate the moved window
3. Do some work on Desktop1
4. Move to Desktop2 and hit alt + click on some window
5. Instead of moving window at Desktop2 it's moving window at the same mouse position at Desktop1

It also works properly if you click on a window right before click+alt move. But if you just moved from some other desktop it will break.

Expected behavior It should move and activate only the window under the cursor and in the current virtual desktop.
