+This tests if the caret position is aligned correctly w.r.t. composited scrolling.

+The important bit is that the "invalidate paint rectangle" invalidation has a position of about 1000px in the

+y direction.

+ <input id="text" style="line-height: 1; font-size: 10; padding: 1px 0px 1px 1px; width:200px;"/>

+</div>

+<script>

+window.testIsAsync = true;

+onload = runRepaintAndPixelTest;

+function repaintTest() {

+ scroller.scrollTop = 200;

+ requestAnimationFrame(function() {
