iOS and macOS

When programmatically triggering a click event on a button which is inside an iframe,
relative URLS are not resolved according to that frame, but to the frame from where the event
was sent.

Included is a testcase which demonstrates the bug. Open the top.html frame, and try to
click the outside button (which clicks the inside button) and the inside button.

Look at the console to see the issue:

> Failed to load resource: the server responded with a status of 404 (File not found) - http://localhost:8080/Testcase/other.html

Instead it should resolve the URL as:

> http://localhost:8080/Testcase/sub/other.html

Which is relative to the frame containing the button.

URLs should be resolved relative to the frame where the clicked element resides.
