False positive for react/display-name

[veloek]

There seems to be a regression in version 7.30.0. Functions like these are now treated like components and trigger the react/display-name rule:

export const demo = (a?: string) => (b?: string) => {
    if (a == null) return null;
    return b;
}

I understand that it might be hard to separate function components from regular functions, but aren't React components always capitalized? Couldn't that be a way to identify them?

This wasn't a problem in version 7.29.4 of eslint-plugin-react.

eslint@8.15.0
eslint-plugin-react@7.30.0

Plus one. You can see the example here. https://github.com/trento-project/web/runs/6502507233

cc @golopot; perhaps some of your refactors broke this?

[golopot]

Yes PR #3276 broke this.

Friendly question: Do you plan to make a new release in the coming days?

@GuillaumeAmat i don't have any specific plans for any release. There will be a release when it's ready.
