@flaviendelangle also opened #4811 fixing this. I leave for both of you to decide who gets credit in the CHANGELOG, although the solution here is smart. I didn't realize we could test only part of the path.

[flaviendelangle]

I did not know about the path either
I already merged my PR but feel free to replace with this one if you want.

We should probably add examples in the interface on the core.

We don't use MuiPage type right now, so we don't see JSDoc from core: /~https://github.com/mui/material-ui/blob/4eef029981b08c77a9c52d0b863e6b5ced279087/docs/src/pages.ts#L17-L20

I'll update the description and make sure MuiPage is used in our repo

We don't use MuiPage type right now, so we don't see JSDoc from core:

I tried to use it but I had a problem and was to lazy to fix it 😆
But yes we should

[cherniavskii]

Yeah, it needs to be addressed in core repo, I've created a PR: mui/material-ui#32715

UPDATE: MuiPage type is now used in MUI X mui/mui-x@a52d3cd (#4854)
