Subject: [PATCH] Ensure that `PDFViewerApplication.{zoomIn, zoomOut}` won't
run when PresentationMode is active (PR 10652 follow-up)
Similar to the `zoomReset` method we need to ensure that this code won't run for zoom events originating within the browser UI itself, since checks in e.g. the `keydown` event handler won't help in that case.
