How to hide an element in a Grid Layout without taking space?

[J0hannes101]

I want to hide a element in a Grid Layout without taking space.
I've tried:

GridLayout {
    Row {
        TextEdit {
            //colspan: 5;
            text: output_consol_text;
            read-only: true;
            visible: enable_console_checkbox.checked;
            has-focus: false;
            height: enable_console_checkbox.checked ? self.height : 0px;
        }
    }
}

which wont work --> "The binding for the property 'height' is part of a binding loop"

Since conditional elements aren't yet supported for grid layouts, it's not an option.

Having an if expression would be nice, but those do not work in GridLayouts yet :-(

This should work:

GridLayout {
    Row {
        TextEdit {
            height: enable_console_checkbox.checked ? self.preferred-height : 0px;
        }
    }
}

Unfortunately that doesn't work for me, here my code:

import { CheckBox, TextEdit } from "std-widgets.slint";

export component AppWindow inherits Window {
    GridLayout {
        padding: 50px;
        spacing: 5px;
        Row {
            text_box_input := TextEdit {}
        }

        Row {
            enable_console_checkbox := CheckBox {
                text: "Enable Output Console";
            }
        }
        
        Row {
            TextEdit {
                read-only: true;
                visible: enable_console_checkbox.checked;
                has-focus: false;
                height: enable_console_checkbox.checked ? self.preferred-height : 0px;
            }
        }
    }
}

This is, what it should look like (if i uncomment the height line, but then it will take up space even if not visible):

This is, what it looks like with the line:

I also get some error massages, when using the cosmic Theme, which i dont get with the Qt backend, but still looks the same:
