How do I change the tray icon name when it's hovered?

[pipipear]

I'm trying to change the text that is shown when the tray icon is hovered over. The title property doesn't seem to affect this. Is there a value intended to control the title shown?

It is menu.tooltip

[pipipear]

It is menu.tooltip

menu.tooltip doesn't affect this either unfortunately

for me this does not works too.
