Surprise "Typographer"

Many, probably, like me, use one wonderful tool in everyday life. Not so long ago, I noticed that my old friend began to behave a little capriciously - img.artlebedev.ru is added to the <img> tags, if the full url is not specified :)

For example, from <img src = "/ image.jpg"> it turns out
<img src = " img.artlebedev.ru/image.jpg ">

It is, of course, clear that the Studio secretly uses the "Typographer" for its own selfish purposes, but the effect was unexpected :)
