Possible fix

You need to choose different workarounds for 2 cases - when overflow="outside" or "inside"
If outside, put padding with var(--removed-scroll-width, 0px) on fixed wrapper
If inside maybe the same, because it the same behavior when is fullwidth.

Another case that needed to be fixed is time when --removed-scroll-width was calculated.
For now is calculated AFTER modal was open. This cause CLS for fullwidth variant, and this is not good.
