What happend?

After upgrading to giu 0.8.0, I cannot use g.Row() to arrange Button widgets horizontally. 0.7.0 has no problem at all

Code example

main.go

```golang g.Row( g.Button("Save").OnClick(func() { if err := conf.SaveConfig(conf.Cfg); err != nil { log.Printf("Configuration save failed: %s", err) g.Msgbox("Warning", "Configuration save failed, please check the log!") } else { g.Msgbox("Tip:", "Configuration saved successfully!") } }), g.Button("Exit").OnClick(func() { systray.Quit() os.Exit(0) }), ), ```

To Reproduce

1. Run my demo
2. will see the crash...

Version

(latest)

OS

Windows11

I need more code, because this one works for me

package main

import (
    "github.com/AllenDang/giu"

    g "github.com/AllenDang/giu"
)

func loop() {
    giu.SingleWindow().Layout(
        g.Row(
            g.Button("Save").OnClick(func() {
                /*
                    if err := conf.SaveConfig(conf.Cfg); err != nil {
                        log.Printf("Configuration save failed: %s", err)
                        g.Msgbox("Warning", "Configuration save failed, please check the log!")
                    } else {
                        g.Msgbox("Tip:", "Configuration saved successfully!")
                    }
                */
            }),
            g.Button("Exit").OnClick(func() {
                /*
                    systray.Quit()
                    os.Exit(0)
                */
            }),
        ),
    )
}

func main() {
    wnd := giu.NewMasterWindow("Issue 807", 640, 480, 0)
    wnd.Run(loop)
}

package main

import (
    g "github.com/AllenDang/giu"
)

func main() {
    w := g.NewMasterWindow("Test", 400, 350, g.MasterWindowFlagsNotResizable)
    w.Run(loop)
}

func loop() {
    g.SingleWindow().Layout(
        // g.Align(g.AlignCenter).To(
        g.Row(
            g.Button("Save").OnClick(func() {}),
            g.Button("Exit").OnClick(func() {}),
        ),
        // ),
        g.PrepareMsgbox(),
    )
}

It seems that the Align (g. AlignCenter) was caused by the use of centering Using g.Align(g.AlignCenter). To will cause the buttons to not be arranged horizontally
