@JoKalliauer Good question. Looks like the `id` attribute must follow the [name](https://www.w3.org/TR/2008/REC-xml-20081126/#NT-Name) token which disallows spaces. Not sure if this is part of the same issue, but here is a test with `use`:

```xml
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <rect id="rect1 " x="20" y="20" width="160" height="70" fill="green"/>
    <use id="use1" xlink:href="#rect1 " x="0" y="90"/>
</svg>
```

![e-use-001](https://user-images.githubusercontent.com/725494/77259542-d3a03500-6c8a-11ea-8792-970e25a7d796.png)

(Batik crashed)

So in this case Chrome ignored the IRI, which is strange.

But if we will insert a space inside the id (since trailing spaces are a bit tricky) the picture is different once again:

```xml
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <rect id="rec t1" x="20" y="20" width="160" height="70" fill="green"/>
    <use id="use1" xlink:href="#re ct1 " x="0" y="90"/>
</svg>
```

I don’t even know what to think.
