Preview button open new tab instead of previous one

[dreamon11]

In admin, after clicking a second time (and more) on Preview button in post editing, a new tab is opened instead of refresh previous tab already opened with new version of the post and focus to this previous tab.

The problem occurs after "Save draft..." mention on bottom of the page.

Problem occurs with Firefox (current version : 62.0.3 (64-bit), Ubuntu) with all addons disabled. Try resetting Firefox, problem still here.

With Chromium (current version : 69.0.3497.81, Ubuntu), the previous tab is refresh but still focus on admin post edit instead of swith to post preview tab.

It's working fine for me in Firefox Version 62.0.3 ( 64-bit ), Ubuntu and Google Chrome Version 69.0.3497.81 (64-bit).

Cool, I didn't know if it's working for you, it's working for everyone. Thanks.

Hi @dreamon11, welcome to WordPress Trac! Thanks for the report.

Could you test ​WordPress 5.0 Beta 1 to see if the issue still happens there?

Thanks for help @SergeyBiryukov!

I managed to solve the problem yesterday: it was evercookie (​https://github.com/samyk/evercookie). Since I remove this code (which activate evercookie):

<script>
  var ec = new evercookie(); 
</script>

it works fine. I don't know why :/
