Descrizione
Is your feature request related to how this polyfill works? Please describe.
Given this HTML
<div id="wrapper">
<div id="anchor" style="anchor-name: --a">A</div>
<div id="target" style="position-anchor: --a">A</div>
</div>
and calling:
polyfill({elements: [wrapper], excludeInlineStyles: true})
Inline styles on #anchor and #target are not polyfilled. It would be useful to not have to pass each individual element, but instead just the wrapper.
Describe the solution you'd like
Adjust the polyfill so that if an element is passed, it AND its entire subtree are evaluated for inline anchor styles.
Describe alternatives you've considered
We could make this opt in, perhaps with a includeChildInlineStyles or an alternate to elements, but I think it's unlikely that people will want to not polyfill children.
