ElyMark: the print page runs none of the document's scripts (M-15)

WebView::open_inert makes a browser with JavaScript off; ElyMark's
staged print page uses it. webprobe opens one page both ways: the
scripted copy must report, the inert one never.

The CEF router drops a query that lacks onFailure, and queries made
before the router is ready are lost; agents.md says so.
