_XfceTasklistChild::n_windows broken in git
Steps to reproduce this issue:
- Open "Window Buttons" (tasklist plugin) preferences and set "Window grouping" to "Always"
- Open application "A" on desktop 1 (example application: Google Chrome)
- Open another instance of the application "A" (Ctrl+N in Google Chrome)
- Move the window opened in step 2 to desktop 2
- Repeat: Switch to desktop 1, switch to desktop 2
Expected outcome: There is no number "2" shown on the window buttons of application "A", because each desktop contains only 1 window of app "A".
Actual outcome: Some of the window buttons are showing the number "2".
