It is super annoying to be clicking back and forth through tabs only to have some text erroneously highlight and then stay that way.
It's more annoying when your web site won't let me copy a package tracking number to paste into my chosen package tracking program. Maybe I don't want to use your system. Maybe the program I have is better.
Just because a web dev can't think of any reasons someone would want to copy text doesn't mean the reasons don't exist. It just means the developer lacks imagination.
That is not what they meant and you know it. They were talking about buttons labelled "OK", "Back", or "Confirm". Buttons that wouldn’t be selectable in a native app either, but somehow we don’t complaints about that here.
