FYI, the article links to a Chromium issue from 2013:
https://bugs.chromium.org/p/chromium/issues/detail?id=168988
which links to another issue from 2012.
Edit: My purpose was to confirm the bug has been "known" for awhile, not to take away credit for you reporting the bug years ago. Congrats for independently discovering it before many people (such as myself) became aware of it.
