Description
Feature Request
On the web, if you have an svg within another svg, you can reference the defs in the parent svg from the child - ids are global after all
Take this example,
<svg>
<defs>
<path id="a" d="…"/>
<path id="b" d="…"/>
<path id="c" d="…"/>
</defs>
<use href="#a"/>
<svg x=…>
<use href="#b"/>
</svg>
<use href="#c"/>
</svg>
This crashes - and it does make sense why it does
But it might be possible to fix this use-case by allowing the child to look up through the svg parents to find the relevant area
Why it is needed
This shows up a lot with the new mathjax 3 svg output using fontCache: 'local' - large brackets are represented in the same format as the example I gave above
Possible implementation
If RNSVGSvgView held an optional reference to a parent svg, this might be possible. Unsure of Android implementation
Code sample
