The removeUnknownsAndDefaults plugin was removing attributes that were used in CSS selectors, which is problematic because that breaks styles!
We should be checking if that attribute is used as part of an attribute selector before we commit to removing it.
I've implemented it to only check for the existence of an attribute selector that references the key, rather than actually compare the value, because attribute selectors are complicated. For example:
[preserveAspectRatio]
[preserveAspectRatio=]
[preserveAspectRatio^="x"]
In future, we can explore making a more robust utility. But for now, let's at least not break SVGs.
