 * Select mode shields iframes from the pointer so presses over an embed reach
 * this document instead of the embed's own (often cross-origin) one. The hit
 * element is then whatever sits behind the frame, so lift the shield for one
 * native hit test to find the frame the user actually pointed at. A frame
 * injected as raw HTML has no React source, so prefer its nearest
 * React-rendered ancestor, which the agent can edit. React 19 renders <body>
 * too, so stop below it: a widget script appends its frame straight to the
 * body, and selecting the frame beats selecting the whole page.
