Work-around for URL fragments resolving against about:blank

Bug 10459904

The upstream review for this issue (http://crbug.com/291747) is complex
and will take time to land, so in meantime applying a smaller special
case workaround in android tree. This will be reverted when the fix from
trunk is ready.
