/* FUEN fix ------------------------------------------------------------------
   Stops the Chart.js hidden resize-detector iframe (class "chartjs-hidden-iframe"),
   used by the article "Downloads" chart, from stretching into a full-screen
   invisible layer that covers the page and blocks clicks on the PDF button and
   the breadcrumb links (Home / Archives / issue).
   This is plain CSS (not LESS), loaded via Settings > Website > Appearance >
   Journal Style Sheet, so it applies even if the theme's compiled CSS is cached.
