Steps to reproduce the problem:
I know this is by design but somebody has to realize this was a wrong decision that needs to be reverted.

1. right click on a tab

What is the expected behavior?
There used to be an item called "mute tab", that would mute that tab. That made sense.

What went wrong?
Now it's called "mute site" instead of "mute tab" and, consistently with its name, it will mute the site, not the tab, which means:
1. if you navigate to another site in the same tab, it will be unmuted. Wrong.
2. Even worse, if you open the same "site" (which apparently is a vague term that actually means the same DOMAIN) in another unrelated tab at a later time, it will be muted by default.

and the worst of all:
3 - you can't have open several pages belonging to the same domain in different tabs and mute only one or only some of them.

This is nonsensical and annoying. 

(3) alone should be enough to see how ridiculously wrong this new design is.

Consider this trivial, common use case:

- I open a youtube video on a tab
- I open a different youtube video on a new tab.
- Now I am interested in the latest I have opened, so I right-click on the old tab and mute it, obviously expecting to keep hearing the new one, but nope! they are both muted, and I can only unmute or mute both. Simply ridiculous, absolute nonsense.

Not to mention EVERY other item in the tab right-click menu acts on the tab, while this one acts on the site: this is inconsistent, unexpected, and confusing.

Did this work before? Yes very recently

Chrome version: 64.0.3282.167  Channel: n/a

It's very worrying to see so many plain wrong design decision that have been taken recently in Chrome.
Out of the top of my mind: explicit re-navigation to the current URL treated as a refresh, and now this. But there have been more. Has Google hired people from Apple or something?
