> ... the page count should now be perfectly aligned with the article name As far as I can tell, that'll only happen if you've hidden the share icons.

Judging by the current "experiment" version of the button, it'll look like this: https://i.imgur.com/V9MwJUb.png

First, the edit/talk buttons were moved to a separate line, then they added the share icons, and now this will make the header taller again… Perhaps they're planning adding ads under the page title, and need more vertical space there!

Edit: looks like the share icons have been disabled with this update, for an overall slight reduction (~5px) in the total header size. Rejoice!
