Webview leaves a yellow border around links and form input field on ajax requests. The link or field is not in view anymore but yellow border stays. With the field it is even worse - it looks like the whole input field is still on the page. We did not find a pure javascript solution so we developed a hack which simulates arrow down and arrow up events. Unfortunately this required changes in native code apk, so it does not help the one we submitted to the Google Android Challenge.
