Container padding not equal to row/column padding (v5)

[truebluepl]

Hi,
in Bootstrap V5 alpha container left and right padding is not equal to row/column margin/padding like in version 4/4.5.
It doesn't matter class container, happens in all .container(-*) classes.

For example: https://jsfiddle.net/fLqjp2av/

Why has it changed and container padding is set to 1rem instead of calc(var(--bs-gutter-x)/ 2)?
