Issue 4510: tailwind-scrollbar-hide v4 import

Source of truth

• Source type: GitHub issue
• Source id: #4510
• Title: tailwind-scrollbar-hide should be imported as @import "tailwind-scrollbar-hide/v4";
• URL: https://github.com/udecode/plate/issues/4510
• State: open
• Task type: bug investigation, likely code fix
• Expected outcome: confirm whether current CLI/template output still emits the wrong Tailwind v4 syntax, and fix it if still valid
• Caveats: issue is old, so first confirm it still reproduces on current code before changing anything
• Likely areas: template CSS, registry/CLI file generation, docs if they still describe the old syntax
• Browser surface: no direct browser proof required unless the fix changes rendered UI

Plan

1. Search current codebase and templates for tailwind-scrollbar-hide usage and identify generation path.
2. Confirm whether the current generator still ships the old @plugin syntax for Tailwind v4 consumers.
3. Apply the smallest fix in source files that own generated output.
4. Run targeted verification for the touched package/template path.
5. Decide whether issue sync-back or PR work is warranted based on whether code changed.

Findings

• The repo still contains @plugin "tailwind-scrollbar-hide"; in app/template CSS and a registry style item that installs tailwind.config.plugins = ['tailwind-scrollbar-hide'].
• The upstream package docs for [email protected] recommend @import "tailwind-scrollbar-hide/v4"; for Tailwind v4.
• Current Tailwind 4 behavior does not treat the existing plugin form as broken:
  • @plugin "tailwind-scrollbar-hide"; compiles successfully.
  • @import "tailwind-scrollbar-hide/v4"; also compiles successfully.
  • The generated scrollbar utilities are effectively the same for current browsers.
  • The only observed output delta is that the @plugin path keeps -ms-overflow-style declarations, while the /v4 import drops them.
• Conclusion: issue #4510 no longer describes a live bug on the current stack. At most, it is a cleanup/docs-alignment request.

Progress

• Fetched issue and comments with gh issue view.
• Loaded task, planning-with-files, and learnings-researcher instructions.
• Searched repo for tailwind-scrollbar-hide references.
• Verified upstream package guidance from the installed [email protected] README and exports.
• Reproduced both Tailwind v4 compile paths locally and diffed the emitted CSS.
