Safari - iOS .getCoordinates().onPage() is acting like .getCoordinates().inViewport()

The problem

I have a test that clicks a button which scrolls the page down to a particular section. I then assert that the heading is within the browser’s viewport. On iOS .getCoordinates().onPage() is acting like .getCoordinates().inViewport().

Environment

• Appium version: 1.53
• Desktop OS/version used to run Appium: OS X 10.11.6
• Mobile platform/version under test: iOS 9.3.5
• Real device or emulator/simulator: iPhone 4S
• Appium.app

Details

My problem is when the following line executes on Appium with iOS: long headingHeight = element(By.cssSelector("h3#objective")).getCoordinates().onPage().getY();

On iOS the figure returned is 0 (which would be correct if I was asking for .getCoordinates().inViewport().getY();) Executing the same test on Android returns the correct result.

This is a web test for the mobile web, not a web view or native app.

Code To Reproduce Issue

driver.get("http://appium.io/slate/en/master/?java#");
wait.until(ExpectedConditions.presenceOfElementLocated(By.linkText("Appium GUI"))).click();
Locatable heading = (Locatable) driver.findElement(By.cssSelector("#section-appium-gui>h1"));
System.out.println(heading.getCoordinates().onPage().getY());

Clone here

For this example, on Android, the position is returned in the hundreds of thousands (which is correct , as you have to scroll pretty far to get here). On iOS, the response is -2 (which would be reasonable accurate if I was asking for onScreen or inViewPort.

@hazmeister can you include a link to a gist of your appium log output?
