Yep. I do. But I sussed out the "why", and now I guess I'm looking for a "suggested fix".
I use the "Tabs To The Front" extension (which forces newly opened tabs to the front/focus because why on earth is that not the default and Chrome incapable of even doing it). https://chrome.google.com/webstore/detail/tabs-to-the-front/hiembaoomcehoiehhdldabfgnmphappc
If that extension is enabled in Chrome (even if it's disabled in the extension itself, which it has as an option) it seems to interfere with that process. :-/
Any suggestions (beyond the obvious "don't use the really useful extension") would be really helpful.
