[PP1] Add tests for the new feature to change the logo

🐛 Enhance Navigation admin workflow with Managed Tabs. Needs review
logo as landmark for layout related page workflow problems if other placed blocks are removed (breadcrumb, local tasks, layout has hidden logo.

Can this be addressed only for what is in core right now and updated with any other changes later?

yes, of course we should begin. Am just linking this new aspect of logo use.
🐛 Custom Navigation logo is disconnected from new Layout template Fixed . I'll see about this fix and should be able to start some related tests for file and display as base.

This may not be needed b/c 📌 Adjust custom navigation logo dimensions on upload Fixed adds functional tests for this feature. It's close to being committed. Lets postpone on that one.

Tests were also added and are already present for this feature as part of 🐛 Custom Navigation logo is disconnected from new Layout template Fixed .

I think we're save to close this one. We already have test coverage in place for this, and it will grow as part of 📌 Adjust custom navigation logo dimensions on upload Fixed .

Closing as outddated.
