Describe your issue

mx-auto in v3 had a more box sized approach while in v4 it does fullwidth (not even sure if its working).
Just wanted to know if thats a known issue.
Other than that v4 is a Banger GJ guys!

mx-auto in v4 still produces the same CSS as v3 for me:

.mx-auto {
  margin-left: auto;
  margin-right: auto;
}

Could you confirm whether this is the case for you? If so, it could indicate a some other unexpected CSS behavior and for that, a minimal reproducible example could help please!
