Local previews not rendering properly in 0.41.0 release

[karenzone]

Describe the bug

My local previews are not rendering properly after I upgraded to 0.41.0.

Expected behavior

I expect beautiful previews at http://localhost:3000/ that automatically refresh on each Save.
Yes, docs-builder has me spoiled.

Steps to reproduce

1. Upgrade docs-builder to 0.41.0.
2. Serve up docs.
3. Make a change to a doc file, and save it.
4. Go to http://localhost:3000/, and check results.
5. See weirdness.
