Should this be marked as fixed now?

Works great, thanks! 

Any idea on when is this fix going to be released? Thanks in advance.

Same question here. When will this fix be released?

This is still happening in Chrome 61.0.3163.91 in headless mode

It'll be in 62.0.3175.0 and above.

But when it will be released approx?

See https://www.chromium.org/developers/calendar.

Waiting for it!

It is not still not working in Chromium 70.0 and puppeteer 1.7.0 in windows.
