"Open windows on current screen" does not appear to work on Linux + i3 wm

**To Reproduce**
Steps to reproduce the behavior:
1. Open CopyQ on left screen (via `copyq toggle`)
2. Close CopyQ window
3. Move focus to the right screen
4. Open CopyQ again

**Expected behavior**

CopyQ should have opened on the right monitor that is currently focused.

**Actual behavior**

CopyQ opens on the same position that I closed it at, which means it opens on the left monitor.

Interestingly enough, it actually opens on the right monitor for a split second and then moves back to its previous position.

**Version, OS and Environment**
(Get details from `copyq version` command if possible.)
