Some components stopped overriding styles, i think after migration to emotion.
For example Typography and Badge. I tried to use className and classes: { [class] }, but none of the ways works.
In devTools, I see That there are styles but their priority is lower than default theme styles.


If you try to change the version of @material-ui/core then you can see, that:
Typography stopped overriding on 5.0.0-alpha.20, and work on 5.0.0-alpha.19
Badge stopped overriding on 5.0.0-alpha.19, and work on 5.0.0-alpha.18
