### Bug Fix

- Listen to `resize` events correctly in `useBreakpointIndex`. This hook is used in `useResponsiveValue` and consequently in the `Flex` and `Grid` components ([#33902](https://github.com/WordPress/gutenberg/pull/33902))
- Fixed RTL styles in `Flex` component ([#33729](https://github.com/WordPress/gutenberg/pull/33729)).
