Form dialog validation becomes valid if one input field is valid

Checklist

[X] I have searched the issue tracker for open issues that relate to the same problem, before opening a new one.
[X] This issue only relates to a single bug. I will open new issues for any other problems.

Describe the bug

In Fyne version 2.4.5, the dialog form validation behavior has changed compared to version 2.2.0. In version 2.2.0, the form remains invalid until all input fields are valid. However, in version 2.4.5, the form becomes valid if at least one input field is valid, which is not the expected behavior.

How to reproduce

Create a form with multiple input fields. (dialog.NewForm)
Set up validation for each field.
Run the application using Fyne version 2.4.5.
Observe that the form is marked as valid if at least one input field is valid.

Example code

The complete project can be found on my GitHub Page.

The function to create the Dialog Form, in toolbar.go:

func (app *Config) addHoldingsDialog() {
    addAmountEntry := widget.NewEntry()
    purchaseDateEntry := widget.NewEntry()
    purchasePriceEntry := widget.NewEntry()

    app.AddHoldingsPurchaseAmountEntry = addAmountEntry
    app.AddHoldingsPurchaseDateEntry = purchaseDateEntry
    app.AddHoldingsPurchasePriceEntry = purchasePriceEntry

    dateValidator := func(s string) error {
        if _, err := time.Parse("2006-01-02", s); err != nil {
            return err
        }
        return nil
    }
    purchaseDateEntry.Validator = dateValidator

    isIntValidator := func(s string) error {
        if _, err := strconv.Atoi(s); err != nil {
            return err
        }
        return nil
    }
    addAmountEntry.Validator = isIntValidator

    isFloatValidator := func(s string) error {
        if _, err := strconv.ParseFloat(s, 32); err != nil {
            return err
        }
        return nil
    }
    purchasePriceEntry.Validator = isFloatValidator
    purchaseDateEntry.PlaceHolder = "YYYY-MM-DD"

    // create a dialog
    addForm := dialog.NewForm("Add Holding", "Add", "Cancel", []*widget.FormItem{
        {Text: "Amount in toz", Widget: addAmountEntry},
        {Text: "Purchase Price", Widget: purchasePriceEntry},
        {Text: "Purchase Date", Widget: purchaseDateEntry},
    }, func(valid bool) {
        if valid {
            amount, _ := strconv.Atoi(addAmountEntry.Text)
            purchaseDate, _ := time.Parse("2006-01-02", purchaseDateEntry.Text)
            purchasePrice, _ := strconv.ParseFloat(purchasePriceEntry.Text, 32)

            holding := repository.Holdings{Amount: amount, PurchaseDate: purchaseDate, PurchasePrice: int(purchasePrice)}

            _, err := app.DB.InsertHolding(holding)
            if err != nil {
                app.ErrorLog.Println(err)
            }

            app.refreshHoldingsTable()
        }
    }, app.MainWindow)

    //size and show the dialog
    addForm.Resize(fyne.Size{Width: 400})
    addForm.Show()
}
