In twig, whenever a comment starts the first non-empty line following an opening tag, the attributes are forced onto a new line and indented.

<div class="container text-white-90">

  {# brand/ logo #}

becomes

<div 
  class="container text-white-90">

  {# brand/ logo #}

I'm using the Twig Language VS Code extension, but this also happens on the website demo.
