Title: Fixes bug where img elements without the realSrcAttribute disappear in Firefox

Fixes bug where img elements without the realSrcAttribute disappear in Firefox.

Original code attempts to replace the src of all img regardless of whether there is any realSrcAttribute. This means that user cannot create a page where certain images are lazily loaded while others are not.
