@DiegoAndai, I see this was fixed in #42358. Do you know why it's still showing in the demos on CodeSandbox or StackBlitz? Is the latest @mui/system not being built correctly? Also, it isn't broken if I render this on a new StackBlitz: StackBlitz Link.

Seems to be related to #42747. Looking into it.

and yes @DiegoAndai , by adding @mui/system@next, it fixed the issue

Fixed in 6.0.0-alpha.13 (#42768).
