Sibling self closing tags become nested

Expected Behavior

A sequence of multiple self closing tags can be parsed.
Example:

<circle id="pointA" cx="100" cy="350" r="3" /> <circle id="pointB" cx="200" cy="200" r="3" />

<tag1 /> <tag2 />

seem to be parsed as:

<tag1> <tag2> </tag2> </tag1>

so tag2 becomes a child of tag1.

For example try:

parse('<circle id="pointA" cx="100" cy="350" r="3" /><circle id="pointB" cx="200" cy="200" r="3" />')

I wonder if maybe this could be a domparser issue, not specific of this repo.
