[QA] Firefox doesn't scroll items into view in browser tests

[Dan Duvall]

According to the WebDriver specification, Firefox "SHOULD try to scroll the
element into view." [1] In other words, it's recommended but the FF
webdriver isn't violating the spec when it doesn't.

Take a look at the watir-scroll gem. It essentially does the JS scrolling
that you mentioned (and those SO posts mention) but at least you won't be
reinventing the wheel. [2] And please let us know if it works reliably as
it might be worth including in mediawiki_selenium or at least recommending
in the docs.
