Images are not wrapping to next line in fancy browser

I have installed Qt creator in my windows 8 machine. I have compile and run the fancy browser sample from the WebKit samples. It successfully compiled and displays websites.

I have attached two HTML documents, both HTML documents are having same behaviour on other web browsers. But the fancy browser behaves differently for the first html.

The both HTML files contains two images with 300 pixels width each, the total width of the HTML is above 600. Now I have resize the fancy browser window size less than 600. It does not wrap the images to next line, instead it created scrollbars for first HTML.

For the second HTML, the browser wraps the images if resize the window less than 600. 

The only difference between the two HTML files is space between the image and span HTML tags. 

Note: Both HTML files wraps the images if I resize the windows of other browsers. (Chrome, Safari, IE, Gecko).

Please fine the documents and screen shots form attachments.
