Besides #3133098: gin--classic-toolbar class given although toolbar not present I see two more styling issues when using the classic toolbar. I am using alpha11 to avoid seeing potential issues from the fix in #3125121: CSS/JS files missing for anonymous users (although the same issues also happen with latest dev).
1. Header style issue

See the gap between the header and buttons.
I'm not seeing this when the gin--classic-toolbar class is removed.
2. Sticky header position issue

saschaeggiPlease check the latest dev :)
Comment #5
anruetherThanks for the quick response (once again :)
1. is gone and for 2. I see some quirks when the header sticks for the first time after a page reload (Alt-F5) or cache rebuild.

saschaeggi@anruether the question is if this is related to Gin. Can you maybe try if you have the same behaviour in Claro as well?
Comment #7
saschaeggiUnrelated but is the "Admin Toolbar quick search" part of the Admin Toolbar module?
Comment #8
anruetherRight that happens in claro (and in seven ;) as well.
Yes, it was merged into admin_toolbar as a submodule, see the old project page: https://www.drupal.org/project/admin_toolbar_search
Comment #9
saschaeggiWas that the one you talked about? If yes, feel free to create a ticket and add it to the Roadmap :)
Comment #10
anruetherYes thanks! Actually atm I prefer coffee over the search toolbar. But I have something else as a feature request ;)
