Created attachment 259473 [details] Video The icon stays in the edited state after being reset.

I vaguely remember seeing this a few times in the past, but I could never get it to reproduce reliably. Do you know what website you were on when you made the attached video?
This was the apple.com home page.
This is also being added at the same time as https://bugs.webkit.org/show_bug.cgi?id=148254. I will close this bug once it is confirmed to be working.
This was fixed in r194737.
