> this issue is occurred only in EFL, but it can be occurred in both QT and EFL.
> this issue is that when MiniBrowser launchs with html file,
> WebChromeClient send the contents size to UIProcess.
> However because it's not sync type message, there is a time gap between WebProcess and UIProcess.
> So if we send the contents size message to UIProcess more than twice fast,
> UIProcess can not handle the messages at right time.

> Like this,
> WEBPROCESS virtual void WebKit::WebChromeClient::contentsSizeChanged(WebCore::Frame*, const WebCore::IntSize&) const 127 8
> WEBPROCESS virtual void WebKit::WebChromeClient::contentsSizeChanged(WebCore::Frame*, const WebCore::IntSize&) const 800 564
> UIPROCESS void WebKit::PageViewportController::didChangeContentsSize(const WebCore::IntSize&) 127 8
> UIPROCESS void WebKit::PageViewportController::didChangeContentsSize(const WebCore::IntSize&) 800 564

> Miss-match the contents size between WebProcess-side and UIProcess-side makes a huge scale factor.
