Layouts in layouts picking wrong template

The selected layout from the library overrides all view displays.
It should probably check whether the option "Allow content editors to use stored layouts" is enabled on a specific display or not.

I'm not sure that this is the right solution, but it will fix the problem.

Thanks for the patch, we need a test here too

   We can inject this

Patch update, including the test as well.

Thanks

I fix the test. It should pass now on Drupal 8.8.
