Opera Bug #364708

Setting the scrollTop value of a textarea while it is hidden has no effect

Affects up to Opera 10.51

Opera (version listed above) fails by not scrolling the textarea at all.

Compared to other browsers: FF fails this test, setting the scrollTop to 0 just by making the textarea hidden. IE6 and IE7 pass this test, while IE8 fails. Safari and Chrome both fail, also setting the scrollTop to 0.
