Can't set cookie in Chrome Dev tools on localhost

Question

I'm trying to set (change) cookie in Chrome Dev tool, but it only stores the name, not the value.

Steps:

1. open page at localhost:3000
2. open dev tools
3. add new cookie
4. set name
5. set value
6. refresh page

Actual result: the cookie with its name is there, but value is empty.

Funny part - this was working a couple of days ago, can't think of what has changed since then.

OS - MacOS v. 10.14.3 Chrome - v. 73.0.3683.86 (Official Build) (64-bit)

Also I noticed the cookie is highlighted in red color (see MyCookie on the screenshot).

Setting cookie for this page works just fine in Firefox.

Already tried:

1. open page from 127.0.0.1:3000 instead of localhost
2. restart chrome
3. restart OS

With the new versin of chrome Max-age of cooke can set in following way using
dev tools -> console set document.cookie manually.
document.cookie='token=1234'.
We will get following things Cookie Name: token
Cookie Value: 1234
Expires / Max-Age: 2019-12-26T15:22:22.000Z
