Dialog: ignores `focusOnShow={false}` when `showHeader={false}`

[adrianhurt]

Describe the bug

When a Dialog has the prop showHeader to false, the focusOnShow is ignored when is set to false, so it will always be focused. This is specially annoying for the case that the first input is a Calendar, because it is focused even before showing the Dialog, so the Calendar's overlay is placed behind the Dialog on the top-left corner. It can be seen on the reproducer

<Dialog
    showHeader={false}
    focusOnShow={false}
    ...
>
    <Calendar value={date} onChange={(e) => setDate(e.value)} />
</Dialog>
