[2.0.0-rc3]  Duplicate blocks when nested ComponentLayout with Layout Builder

pdureau → credited grimreaper → .

i will take that one

Let's review this very carefully. It is only one line of code for now, but Layouts plugins are used in some weird ways in Drupal, and we don't want to fix on one side to break in the other.

      $build[$region_name] = $regions[$region_name];
      $build[$region_name] = &$build['#slots'][$region_name];

Also, let's update the comment before with tne new situation:

      // For layout builder we need to pass slots also
      // direct to the build array. They are needed to generate contextual
      // links and other surrounding markup.
      // This makes field layout forms empty.
      // Not sure how to handle this. Should we support field_layout?

Hi,

Thanks a lot for the bug fix!

I confirm it fixes the issue.

i let christian update the comment on the original code.

Looks good for me. Also field_layout with forms works now. Great. I added a check to test if the layout builder specifcs are added.
