js: prefer some puzzle size even if loading isn't complete The js_canvas_get_preferred_size() function was declining to suggest a size for the puzzle if document.readyState wasn't "complete". I think my idea here was that if the document wasn't fully loaded then I couldn't trust the size of the containing <div>. While this was true, declining to provide a size didn't help much since the puzzle still needed a size, and the size of the containing <div> was the best guess we had. Now that function always returns the size of the containing <div> if it exists. This appears to mean that puzzles don't show a brief flash of being the wrong size on KaiOS. That was particularly visible with Flood, where the wrong-size version had borders around the tiles that the right-size version lacked. The containing <div> isn't used on the standard Web versions, so there's no change to behaviour there.
