Describe the bug

I have the following code for DatePicker:

<DatePicker
            id="dato"
            name="dato"
            fluid
            show-icon
            show-button-bar
            dateFormat="dd.mm.yy"
          />

And I set the initial value for dato = new Date(). Before version 4.4.0, that resulted in todays date as the chosen date for DatePicker and showing 10.10.2025 in the input field. But since version 4.4.0, the DatePicker input field is blank and clicking in the input field, shows the following text:

Fri Oct 10 2025 10:42:19 GMT+0200 (Central European Summer Time)

After choosing a date in the DatePicker, then the date shows as it should in the input field.

I am guessing that this is not a new feature, hopefully, so can you please fix this...

btw, this happends when using the DatePicker together with primevue forms.
