Cherry-picked from Qt upstream (commit e488f852fa18c2afc2842a88eff8f66ad4105a45). Original patch source: https://download.qt.io/official_releases/qt/6.11/CVE-2026-6210-qtsvg-6.11.diff Fix: Test types of nodes before downcasting them. A bad cast in QSvgMarker::drawHelper led to endless recursion resulting in a heap overflow. While fixing that, another similar case was also fixed.
