Focus on Blocks is not removed when focus switches to other field

When I click in a block, it gets correctly highlighted and when I switch to antother block the highlight jumps to that block, but when I focus another field, outside of the blocks-field, the highlight on the block stays and the highlight on the field is set correctly, but now you have two highlights on the same page, which can be very confusing when using nested blocks in a custom built block. especially when the action bar of the block is still active.

See picture down below:

Outline of my blueprint definitions for reproduction:

columns:
    - width: 2/3
      fields:
          excerpt_post:
              type: textarea
              buttons: false
              label: Einleitungstext (Abstract/Auszug)
              required: true
              help: Abstract, der nach dem Titel und vor dem Beitragsinhalt angezeigt wird
          post_content:
              type: blocks
              label: Beitragsinhalt
              fieldsets:
                  text:
                      label: Text
                      type: group
                      fieldsets:
                          - heading
                          - text

Yes, I can reproduce this, could you please create an issue on GitHub?
