Detailed Description

Renders the (HTML-ish) content captured inside a <foreignObject>.

This is an extension point on purpose: ForeignObjectSimple below only understands a small, deliberately shallow slice of HTML5 – it strips every tag (div/span/p/i/b/...) and just draws the remaining plain text centered in the foreignObject's box, using the font/fill already inherited through the normal SVG/CSS cascade. That's enough to cover what tools like Mermaid actually emit (a single short, non-wrapping, centered text run per foreignObject), without pretending to be a real HTML/CSS layout engine.

A more complete renderer (e.g. one backed by litehtml) can be hooked in later without touching SVGForeignObjectElement itself: implement this interface and call SVGForeignObjectElement::setRenderer() (or replace ForeignObjectSimple::instance() below) to swap it in.
