What is the current behaviour? Not possible to do a successful preact build when using preact-async-route for code splitting due to:

× ERROR ReferenceError: document is not defined

Gist with full log

If the current behaviour is a bug, please provide the steps to reproduce.

TL;DR sample repo

1. Create a new application through CLI
2. Pick typescript (I am not 100% sure this is relevant in some way?)
3. Install preact-async-route
4. Update at least 1 route to use Route from async-route package and use the getComponent prop
5. Run preact build

What is the expected behaviour? The build to complete successfully and produce all of the expected files

Please mention other relevant information.

Please paste the results of preact info here.
