Invisible widgets not supported for nested filters in search views

To reproduce, add a nested filter in a search view and restrict it to the "Technical Features" group for example. E.g for the ir.modules search view I appended:
                        <field name="category_id">
                             <filter name="no_hidden" help="Hide technical modules"
                                    icon="STOCK_REMOVE" groups="base.group_no_one"
                                    domain="['!', ('category_id.parent_id','child_of','Hidden')]"/>
                        </field>

You can verify that the field_view_get() method adds an invisible="1" attribute to the filter, as well as the corresponding modifiers = {'invisible': true} attribute. Based on this the filter should be hidden, but it is not.

Moving the filter out of its parent field to make it top-level fixes the issue.

PS: please use the value of the 'modifiers' attribute for consistency throughout the web client, instead of the 'invisible' attribute.

Thanks!
