ClearClick false (+) on 3rd-party YouTube with overlain div
Posted: Wed Dec 30, 2015 7:27 pm
With the current stable Fx (43), with a fresh profile having the current stable NS (2.7) as the only add-on, and no changes to NS preferences except to allow the relevant pages, I reliably get ClearClick false positives when there are annotations overlain atop an embedded YouTube HTML5 video. By "reliably," I mean I've seen this through every Fx and NS version for over a semester, but haven't had time to post about it till now. (Possibly related: viewtopic.php?f=7&t=20784 , viewtopic.php?f=7&t=21116 , viewtopic.php?f=8&t=21140 , viewtopic.php?f=7&t=21230 . [Btw: I tried to make these BBCode URLs, but they got false (+) flagged for spam. Perhaps exempt forum-internal links from the forum anti-spam heuristics?])
For example, ClearClick report ID 377801, from this video on Half-life and carbon dating, shows one of several reports I've submitted from Khan Academy. Reliably, on Khan Academy, when I attempt to use the YouTube controls while a "clarification" annotation is overlain, I get a ClearClick warning. On Khan Academy, as with most YouTube videos, I set each video to play at double speed. (To work around a bug in KA in which the video doesn't count as played unless you've loaded every frame, including the few that get skipped when switching playback speed or video quality, I start the video loading, pause it, switch it to 2×, and then resume.)
Rather than editing their videos on Khan Academy, when someone discovers an error (such as Sal writing "G" for grams instead of "g" in the linked video), the staff overlays a partially transparent div>span>div>span with the correction. Thus, on every Khan Academy video with a correction, I have to dismiss a ClearClick false positive.
