Qt custom tooltip not working
Qt apps that don't use the standard tooltip show blank tooltips. Tested on Xubuntu 21.04 with Status Tray 0.2.2-1.
instead of what should appear
Note: This also happens with qBittorrent (panel-plugins/xfce4-statusnotifier-plugin#10) and the tooltip may also show the text tooltip of the previous app that was hovered over (panel-plugins/xfce4-statusnotifier-plugin#9)
