Preview cache (seems to) break Markdown preview

[karuboniru]

Current Setup:

• a folder with README.md
• using latest commit in main branch 1f5f90c

Problem:

When Preview Cache is enabled:

• README.md renders when viewing the folder (e.g. this link)
• README.md won't render when previewing this file
  • via workers.dev link, gives error code: 1042 code this link
  • via custom domain name, gives 523 Origin Unreachable, this link
• Downloading the file works, with full markdown file downloaded

When Preview Cache is disabled, the file can be viewed normally.
