OK.  But it's also actually what e.g. MATE's panel (which is a dock too)
uses:
https://github.com/mate-desktop/mate-panel/blob/master/mate-panel/panel-menu-bar.c#L415

There really seems to be something funky in relation to that Keybinder.
GTK emits warning when poping up the menu, I guess because it doesn't
see the "current event".

Initially:
> (menu2.py:24105): Gtk-WARNING **: no trigger event for menu popup

And then, if playing with arrows:

I can't help with that, but I think it's related with the issue ;)
