feat: get currentColor from caller instead of parent (#2521)

# Summary

Fixes #2520
When an element uses `currentColor`, it should look for color in its
caller, not in its parent.
Example: 
```svg
<Svg width="100" height="100" viewBox="0 0 100 100" color="red">
  <Defs color="blue">
    <G color="green">
      <Rect id="a" x="0" y="0" width="50" height="50" fill="currentColor"/>
    </G>
  </Defs>
  <G color="pink">
    <Use href="#a"/>												<!-- #1 -->
  </G>
  <Use href="#a" transform="translate(25 25)"/>						<!-- #2 -->
  <G color="green">
    <Use href="#a" transform="translate(50 50)"/>					<!-- #3 -->
  </G>
</Svg>
```

* `#1` should be **pink**
* `#2` should be **red**
* `#3` should be **green**
