// Secondary-frame input test - a secondary wxFrame (like KiCad's 3D viewer)
// overlapping the main frame's native DOM controls.
//
// The wasm port renders wxChoice as a real DOM <select> with
// pointer-events:auto, while a secondary frame's window div is
// pointer-events:none (clicks fall through to #canvas for the C++ hit-test).
// Without an input barrier for the main window's controls, a click on the
// secondary frame's toolbar lands on the hidden <select> underneath and pops
// its native dropdown (pcbjam: 3D viewer toolbar vs pcbnew's track-width
// selector).
