[BUG] No document preview in Claude Code, despite Home tab supporting it (same account/product)

What's Wrong?

Claude (the app) has two tabs under one account: Home (chat) and Code (Claude Code). Home renders an inline preview when Claude creates a Word (.docx) document. Code does not — a .docx generated in Code is delivered only as a downloadable file card, with no preview and no warning that preview isn't supported there.

What Should Happen?

Since Home and Code are marketed as one product, document preview should work consistently across both, or the product should clearly state upfront that Code doesn't support it.

Error Messages/Logs

Steps to Reproduce

In Home, ask Claude to create a .docx file → inline preview appears.
In Code (same account), ask Claude Code to generate a .docx file.
File is delivered as a file card only — no inline preview.
