Integrate Gin with the new Navitaion Top Bar

I'm working on it.

So far I've pushed the basic support for the new regions in the top bar and to disable the toolbar when navigation top bar is active.

Hey @Jürgen 👋

Can you take a look here?

You'll need to install navigation and navigation_top_bar

@saschaeggi yes, this is on my list for this week.

This is looking great, I like this a lot.

However, I found a couple of issues and my test environment looks like this:

• Drupal 11.x-dev
• Gin with the MR!589
• Enabled navigation and navigation_top_bar

The issues I found:

• When loading a page, the main region takes the full browser width, until the left navigation gets loaded, which is when the main region flips back to the narrower width. I guess that's an issue with navigation, not with Gin, right?
• The action buttons are clickable but nothing happens.
• When opening/closing the right sidebar, this works correct both throws this exception in the browser console: Uncaught TypeError: trigger is null more_actions.js:50:7

Looking into the MR, I wonder how resistant this code is for the various combinations that we may have to support:

• D10 with Gin only
• D11 with Gin only
• D11 with Gin and navigation
• D11 with Gin and navigation and navigation_top_bar

Is there any other combination that I may have missed?

@saschaeggi found the reason for the nonfunctioning action buttons. They no longer have the data-drupal-selector="gin-sticky-${formElement}", but instead data-drupal-selector="${formElement}", i.e. the gin-sticky- prefix is no longer there. I guess, similar changes elsewhere will have additional side effects that we don't want.

Before we can fix those, we should finalize the scope definition on what combination we want to support as raised in #8. We can then implement that accordingly, but I can already foresee that we have to cover a lot of different scenarios with one code base.

That said, I wonder if we should move the navigation support into Gin 5.x and there only support 11.2 and later. Or whatever Drupal core version will have the new navigation in a stable fashion.

This is way too much CSS/twig for me to competently review, but I came here to say that the main pain I see without this fix is the page title not being displayed by the top bar on admin pages.
