1px wide white border on fullscreen

[InternetNutzer]

Describe the bug Going into fullscreen leaves you with a white border, which can be distracting when watching videos that are rather dark

To Reproduce Steps to reproduce the behavior:

1. Go to any video
2. Click on fullscreen
3. Look at the edges of screen
4. See error

Expected behavior The border to be removed when watching in fullscreen

Desktop:

• OS: Arch Linux
• Browser: Firefox
• Version: 124.0.2 (64-bit)

Additional context I've noticed this code snippet, which seems like it was supposed to be a workaround for this exact problem, but I was still experiencing the border

/*remove 1px window border in fullscreen*/
  :root[inFullscreen]#main-window::before {
    opacity: 0 !important;
  }

love your rice, keep up the good work <3
