I'm well aware. I'm saying that the tab should appear to close but persist in the background for a short period of time so that I can Ctrl-Shift-T and get my untouched context back.
EDIT: But if it were an option or an extension, I would gladly enable it to help for 99% of sites I use and either accept the occasional weirdness or blacklist it for Youtube et all
That's my main pain point (I really do think about frequently), but if others are having problems with AJAX-generated forms or whatever, it would help them too.
Another example would be losing your place in on an infinitely scrolling page (yet another web anti-pattern) because you accidentally closed the tab. I would appreciate having a second to correct my mistake before I having to do the"scroll wildly for 30 seconds until it catches up to where I was" song and dance.
