### Contact Details nk@xbuild.com ### Detailed description **Describe the bug** In one self-contained system, Tailwind does generate breakpoint utilities such as md:flex. In another self-contained system (same setup), Tailwind does not generate these utilities - resulting in classes like hidden md:flex staying display: none at all breakpoints. It only works if the same class also appears in another location like somewhere in account-management Once that duplicate usage is removed, Tailwind stops generating the utility entirely. This means the preset content is inconsistently respected depending on the current working directory of the consuming app. **Expected behavior** The content configuration defined in a preset should reliably apply to all self-contained systems that consume the preset - matching the behavior described in the Tailwind documentation. **Additional context** - Adding a content array inside the self-contained system's own tailwind.config.{js,ts} fixes the issue immediately. This suggests that the preset content paths are not merged or normalized relative to the consuming system, even though the docs state that presets can include content. - I also included a video in which you can see we have the utility class in one system (code on the left) which is not applied, but after adding it in another system (code to the right) the tailwind class works correctly. https://github.com/user-attachments/assets/28036cc7-e41c-4691-ac59-da2a1d134b2c ### Severity High ### Is this bug security related? - [ ] This bug is related to security ### Code of Conduct - [x] I agree to follow this project's Code of Conduct
