.NET 8 Blazor components unexpected behaviour

• Two the same interactive components placed in the same place on two different static pages

• The same component instance is render on both pages

• Two different instances are rendered

• Using @key attribute directly on components
• Adding empty component before interactive one on either counter or home page.
• Using InteractiveMode directly on page

• Documentation doesn't have a word about such behaviour
• Hidden dependency between pages
  Let's assume new static page was added to project.

  @page "/newPage"
  <TimerExample @rendermode=InteractiveServer/>
  @*
  Some stuff
  *@

  You can't determine what's gonna happen when you navigate to this page without knowledge about other pages because:
  • If there is other page with matching layout until 'Some stuff' then when navigating only between these 2, the timer would be the same.
  • If there is no page with matching layout, then new component will be rendered no matter from which page you come to this page
