What information was incorrect, unhelpful, or incomplete?

It looks like some css is missing to support border-radius on options popover to support dark mode.

What did you expect to see?

As we have added

option:first-of-type {
  border-radius: 8px 8px 0 0;
}

option:last-of-type {
  border-radius: 0 0 8px 8px;
}

popover should not have square corners with white background when added

html{
  background: black
}
