Checkout (#shipping & #payment) multiple scroll bars in chrome & Edge, in descktop sizes.
This appears to be the new css added in lines 1280 to 1286.
To fix, please wrap the overflows in an @media statement
e.g.
@media only screen and (max-width: 768px) {
	html {
		 overflow-x: hidden;
	}
	body.checkout-index-index {
		 overflow-x: hidden;
	}
}


Checkout (#shipping), onloading in Chrome and Firefox (desktop sizes and not logged in) the page scrolls down to the "Delivery Address" section, on loading when logged in the page scrolls to the "Check delivery area" section (essetually hiding the "Choose shipping address" section).
Note: It does not always occur, possibly due to server speed/load.
This does not appear to occur when using edge.


Checkout (#shipping) errors at top of page, when clicking "Continue to Payment" at the bottom of the page (requires an invalid email address).
The form does not scroll to the top to where the error message(s) are displayed.
The Error Message appears twice
The Error message disapears after a few seconds
The Email Address field is not hightlighted (normally a red border) and no error message is shown by the field
Note this error only seems to occour on the first visit to the page were an invalid email address is used (e.g. g.frizzell@portalpeople.couk), just clicking "Continue to Payment" allows you to continue to the payment page.
