ionic 6 datepicker as popup as it used to be?

Question

I have just updated to ionic 6 and noticed the date picker sits inside the page as a full calendar, where it used to pop up on the bottom of the screen.

I can't figure out how to get it back to how it used to work, here is the code (this hasn't changed since the update to ionic 6):

<ion-datetime formControlName="dob" class="input" placeholder="Select date of birth..."></ion-datetime>
