Layout glitches in production build with CRA

[zeitderforschung]

What package has an issue

@mantine/core

Describe the bug

First of all, thank you for the fantastic v7 version without CSS-in-JS. I have successfully migrated an entire application to v7 and find the new style handling much more straightforward and logical. 👍🏻

Everything is working fine in my development environment so far. But after building the project and running it productively there are some style glitches that do not occur in development. I would be very grateful for a clue as to what could have gone wrong here. I am using a Create React App (CRA) with React Scripts.

Example for strange layout effects on production build:

What version of @mantine/* page do you have in package.json? (Note that all @mantine/* packages must have the same version in order to work correctly)
