showif doesn't deliver events to children of its children

[Kia]

it seems that showif only delivers events to it's children and not their children, considering that often the screen elements are nested, it creates undesirable results while trying it with complex screens.
here's an example:

Code: Select all

transform on_hide_test:
    alpha 0.0
    on appear:
        linear .3 alpha 1
    on show:
        linear .3 alpha 1
    on hide:
        linear .3 alpha 0

screen on_hid_scr:
    default hid = 0
    vbox:
        showif hid:
            hbox:
                button:
                    at on_hide_test
                    text "hide"
                    yalign 0.1
                    action ToggleScreenVariable("hid", 0, 1)
        else:
            button:
                at on_hide_test
                text "hide"
                yalign 0.1
                action ToggleScreenVariable("hid", 0, 1)
