Chrome header regression

[pofider]

With the puppeteer 2.0.0 we use in jsreport 2.7.1 the header template in some cases doesn't display the page number.

I uploaded the test. It doesn't display numbers with jsreport 2.7.1 but works with 2.6.1
Changing the margin from 1cm to 1.1cm helps.

I am not sure if this has something to do with this announced change or not.
puppeteer/puppeteer#5080
It would be good to know if we should just ignore it or change some view port settings.
