addJQuery in hookBackOfficeHeader

[oleacorner]

What is the purpose of the call to $this->context->controller->addJQuery();
in the public function hookBackOfficeHeader() ?

The hook back office header should be used to place module information in the back office header, whatever the controller.

It shouldn't call a controller method.
In particular, the addJQuery is certainly called elsewhere in the back office initialisation
