No*, but I visit reactjs.org regularly, so this could also be due to Google tracking me. In full disclosure, I clicked the article thinking it was about ReactJS. I've never used ReactOS, though I've been aware of the project (and visited their webpage) before ReactJS was even a thing.

Edit: This could very easily be from AdBlock Plus as well, but the tooltip was under the address bar (and it doesn't reappear when I visit reactos.org)

Edit2: I got this when navigating to https://goggle.com also (that's goGGle, not google). Turned off Lastpass and Adblock Plus to confirm it wasn't from them.
