I'm a little confused why the padding on containers,

  padding-right: 1rem;
  padding-left: 1rem;

is 2rem in total, but the row negative margins are -1.5rem in total

.row {
  --bs-gutter-x: 1.5rem;
  /* snip */
  margin-right: calc(var(--bs-gutter-x) / -2);
  margin-left: calc(var(--bs-gutter-x) / -2);
}

This results in 0.25rem of padding on the left and right of the containers, and makes edge-to-edge a challenge. While it doesn't matter much in the examples because they use a white background, it makes edge-to-edge backgrounds a problem. Is this intentional or a bug? Because my interpretation of the documentation is that the negative margins on the rows should exactly counteract the padding on containers. When I set --bs-gutter-x to 2rem, the problem goes away.

Thanks for all the work on Bootstrap v5! I am very excited about the stable release.
