Collapse/Accordion - CSS issue with only one card

[Schnatteraffe]

Hello
I've just used the accordion with cards and on some pages I need only one card. As you can see on the screenshot the CSS messes up the borders. I think it's because the one card is both the first and last child of the accordion.
Regards
Michael

Same issue here:

bootstrap 4.3.1
tested on: chrome 74.0.3729.169, firefox 67.0 on windows 10

My quick and dirty fix was:

.accordion > .card:only-of-type {
    border: $card-border-width solid $card-border-color;
    @include border-radius($card-border-radius);
}

Bottom border already fixed in #28365, but top border isn't rounded.

Fix could be: .accordion > .card:last-of-type --> .accordion > .card:last-of-type:not(:first-of-type) in _card.scss
