Reviewed by Tim Horton and Megan Gardner.
Source/WebKit:
Since at least iOS 11, -[UIScrollView _adjustForAutomaticKeyboardInfo:animated:lastAdjustment:] adjusts the
scroll view's content offset to account for updated keyboard bottom insets. In WebKit, we call this method
whenever keyboard geometry changes (based on system notifications, such as UIKeyboardWillHideNotification).
When switching between focused form fields, we hide the keyboard for the previous focused element prior to
showing the keyboard for the newly focused element. This means that we will actually dismiss the keyboard in the
process of changing the focused element, which posts keyboard geometry notifications, which causes us to scroll
WKScrollView.
On iOS 12, this would be immediately followed by re-presenting the keyboard for the new focused element, which
causes us to adjust the scroll view back to its original position right away; this means that the scrolling that
happens as a result of adjusting for the keyboard insets after dismissal doesn't result in any visible change.
However, on iOS 13, after r239441 and r244546, we now defer scrolling and zooming to reveal the focused element
until later; this means the scrolling that happens as a result of initially dismissing the keyboard now causes a
consistent jump in the scroll view's scroll position (whereas on iOS 12, this only happens rarely, and the jump
is also less noticeable).
To mitigate this, we detect the case where we're moving focus from one element to another; if we're about to
show a keyboard for the newly focused element, then we should avoid scrolling as a result of the impending
"keyboard will hide" notification.

+PASS Did not observe unnecessary scrolling
+
+This test verifies that moving focus between two fields that are at the same y offset does not induce vertical scrolling. To test manually, focus the left field and press any key. Focus should move to the right field, and there should be no scrolling.
+
+On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
