Unfortunately, this is not true. This is still NOT (fully+) fixed in current (73) Chrome/Chromium. +) in most real usage scenarios your cookies will persist, contrary to your/users belief. The even bigger problem, is google employees for a few years (sic!) delaying fix for this. AFAIK press article documenting it is in the works, but you can just jump into chrome bugs discussions and draw your own conclusion if this was prompt and appropriate reaction. So the problem is: 1. it is not yet fully fixed 2. it is MULTIPLE years in this state 3. google knew about it and was interested in keeping it as it is.
