// Workaround for crash in WebKitGTK when loading Fluidd < v1.37.0 or Mainsail < v2.16.1.
// Those frontends use vue-resize, which injects a hidden <object> element for resize
// detection. This corrupts the heap in WebKitGTK regardless of GPU or environment variables.
// The fix patches document.createElement at document-start to neutralize the broken <object>
// hack, and replaces addResizeListener/removeResizeListener with a native ResizeObserver shim.
// See: https://github.com/OrcaSlicer/OrcaSlicer/issues/7210
