Not closing some svg tags

[Tolmark12]

Input :

<line></line>
<ellipse></ellipse>
<path></path>
<polyline></polyline>
<div></div>
<randomtag></randomtag>

Output :

<line>
<ellipse>
<path>
<polyline></polyline>
<div></div>
<randomtag></randomtag>

Is this happening on purpose? If so, it is breaking the display of svgs.

Love the project, thanks for sharing it!
