Temporarily you can fix that by adding mergeSelectors: false in your config.

Another issue related to mergeSelectors: #1967. Both will be fixed by #1973.

Note that: when #1973 is merged, text-#333 will have higher precedence. It's better to avoid using utilities that apply the same CSS properties at the same time.
