Excuse me if there is an existing post for this, but I couldn’t find one.
I don’t believe that the reset button in the Admin Settings panel should appear in the same location as the confirm/cancel buttons as it could easily cause you to lose your setting with a simple double click brought on by loading times, twitchy fingers, etc…
Let me demonstrate:
This just happened to me for that exact scenario. I had a long list of whitelisted onebox domains, and lost them all because of a funky loading issue/impatient fingers. I actually don’t remember reset auto-confirming either, meaning that when you click reset, even though it flashes the confirm/cancel buttons it doesn’t actually allow you to choose one. I can’t say I have used it enough to remember how it always performed, however. If it’s always been that way, I’m not sure that it should be.
It’s not a top priority, but I would recommend simply moving the reset button to a slightly different location to avoid this potential issue, and maybe not auto-confirming on reset?
