Bug 1601532 - Make `test_bug1332876.html` synthesizes on `<span>` element in the `<iframe>` rather than on the `<iframe>` r=smaug 

The timeout is caused by that `iframe.contentWindow` may not receive `click`
event (as far as I've tested, neither `mousedown` nor `mouseup` is fired in
that case) when synthesizing a mouse click over the `<iframe>` element with
parent window.  However, if it synthesizes mouse click with `<span>` element
in the `<iframe>` and `iframe.contentWindow`, `click` event is always fired.
