Native context does not show safari web element when using 1.7.0

Not sure if this is a bug, but it is def an issue for me.

When executing driver.getPageSource() on appium 1.6.5, I can see all the web elements as native elements. For instance buttons and text fields inside the browser.

However, when running the exact same test script on appium 1.7.0 and later, the web elements are not present when executing driver.getPageSource().

Is this expected behavior? Is it possible to configure this in appium somehow?
