Incorrect attribute inside the 4 column twig files

Hello,

I selected the 4 column bricked layout for one of my panel page. I added a block in the Top region of this layout, but that block is not visible on the page. I checked the bs-4col-bricked.html.twig file (inside bootstrap_layouts/templates/3.0.0) and the code for the top content had the following lines of code (code from line 32 to 36)

 {% if top.content %}
  <{{ top.wrapper }}{{ top.attributes }}>
 {{ first.content }} //instead it should be {{ top.content }}
  </{{ top.wrapper }}>
  {% endif %}

I checked bs-4col-stacked.html.twig file and the same issue was present in that. Also, after I changed it to {{ top.content }} the block was displayed on my page.

Can the maintainer please comment on this.
