Both, xfce4-panel as well as xfce4-power-manager depends on libxfce4ui and libxfce4ui depends on gtk2 and gtk3, so you might need to configure .config/gtk-3.0/settings.ini, too.
FWIW I'm using lxpanel and fbpanel, both depend on gtk2 only. I neither have a tooltip setting in my .gtkrc-2.0, nor in the .config/gtk-3.0/settings.ini, but tooltips are shown by the panel.
My guess is that Xfce4 is a gtk2/gtk3 hybrid, still migrating from one to the other, but I might be mistaken.
I don't actually have a settings.ini in that folder. I looked up the GTK+ 3 reference manual, and there is a 'gtk-enable-tooltips' property, but it is deprecated and ignored since 3.10. I created the file and added the line anyway, but that didn't solve the problem.
