npx stencil build broken after update to 1.16.0 (while fine with 1.15.0)

[lxg]

Stencil version:

@stencil/core@1.16.0

I'm submitting a:
[ x] bug report
[ ] feature request
[ ] support request

Current behavior:
After upgrading an existing application to Stencil 1.16.0 and running "npx stencil build" (with or without additional parameters), I get the following output, and the build fails:

After downgrading to Stencil 1.15.0, everything works fine again.

I also have lots of problem with everything around Firebase with the version 1.16...

Like:

[ WARN ] Bundling Warning UNRESOLVED_IMPORT
'rxjs' is imported by ./node_modules/rxfire/firestore/dist/index.esm.js, but could not be resolved –
treating it as an external dependency

This is not an error, but there is no valid package compiled.

Not there in 1.15.

I had the same error about Cannot find name 'describe'. Do you need to install type definitions for a test runner?...
I ran npm run test and it just installed missing dependencies.

Errors are now gone 👍

Confirming that 1.16.1 fixes the issue. Thanks! :)
