/* Syncfusion SfChart — clipPath rect visibility workaround     */
/* ============================================================ */
/*
 * Syncfusion's SfChart wraps each series and its markers in <g> elements
 * with a clip-path that references a <clipPath><rect/></clipPath>. The
 * rect has stroke="transparent" fill="transparent" (so it doesn't render
 * visually) AND visibility="hidden" (presumably to keep it out of the
 * accessibility tree).
 *
 * Some Chromium versions (Edge 148+, observed 2026-05-16) treat
 * `visibility="hidden"` on <clipPath> children as "this child does NOT
 * contribute to the clip region" — making the clip region empty, which
 * clips every painted line/marker to nothing. The chart frame, axes,
 * legend, gridlines all render fine (they aren't inside the clipped
 * group); only the series series themselves disappear.
 *
 * Forcing visibility:visible via CSS overrides the SVG attribute. The
 * rect stays non-visual (fill+stroke are transparent), but its geometry
 * now correctly contributes to the clipPath. Line and markers appear.
