React - Text component - fontSize not computed when `variant` prop is defined in styled-components' `attrs` method

[OlivierFreyssinet]

Hey fellow devs, I’ve just noticed a small bug while using the Text component on LLD, don’t know why I didn’t notice it earlier:

If we pass variant as a regular prop in rendering (e.g in a component that returns <Text variant="h1" />), the fontSize will be applied normally, but if we pass it as prop in a styled component’s attrs like so:

import {Text} from "@ledgerhq/react-ui"
const SomeText = styled(Text).attrs(() => ({variant: "h1"}))``;

the fontFamily and fontWeight are working properly it seems, but the fontSize is not computed at all (it isn’t just overriden or sth like that, i checked the inspector)

Anyone has a clue why? 🧐 I guess it has something to do with how our styled-system is setup but it’s a mystery to me
