- Visit a PDF file like https://commons.wikimedia.org/wiki/File:Sample_Syllabus_for_Wikipedia_assignment.pdf.
- Hover the mouse over the orange text "application/pdf" beneath the first page of the PDF file.
- Now try to click the "read more" link in the text of the popup.
You can't do it, because the popup disappears as soon as the mouse leaves the "application/pdf" text. You can only click the link if you move the mouse via the exclamation icon.
The popup should have a timeout, in order to give the user a chance to move the mouse and click the link.
(Not sure whether this is an OOUI issue or something that can be fixed in PdfHandler itself.)
